1 9-740; Rev ; /04 General Description The MAX748 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a boost switching regulator and two charge-pump voltage-regulator circuits. The boost switching circuit is configured for a +0V output that provides up to 00mA of current from a supply voltage of +.7V to +5.5V. The positive charge-pump circuit is configured for a +5V output that provides >0mA of current. The negative charge-pump circuit is configured for a -5V output and provides >0mA of current. Power for either or both s can be provided from the +.7VDC to +5.5VDC source or from the boost switching-regulator output. The MAX748 EV kit demonstrates low-quiescent current and high efficiency (over 86%) for maximum battery life. Operation at MHz allows the use of tiny surface-mount components. The MAX748 TSSOP package (.mm max) with low-profile external components allows this circuit to be less than.mm high. The MAX748 EV kit can also be used to evaluate the MAX779 IC.

The boost switching-regulator can be adjusted from +.7V to +V with resistors. The positive charge-pump regulator s output can be adjusted up to +5V, and the negative regulator can be adjusted to -5V with resistors. The MAX748 EV kit charge-pump circuits feature PC board pads for a positive voltage tripling and negative voltage doubling output circuits. The MAX748 EV kit can evaluate the MAX779 IC after replacing several components. See the Evaluating the MAX779 section. Jumper Selection Shutdown Mode The MAX748 EV kit features a shutdown mode that reduces the MAX748 quiescent current, preserving battery life. The -pin jumper (JU) selects the shutdown mode for the MAX748. Table lists the selectable jumper options. Positive Charge-Pump Regulator Feedback In the MAX748 EV kit, jumper JU selects which positive charge pump will be regulated: VP, a voltage doubler, or VPA, a voltage tripler. Table lists the positive charge-pump regulator jumper options. Negative Charge-Pump Regulator Feedback In the MAX748 EV kit, jumper JU selects which negative charge pump will be regulated: VN or VNA, a voltage doubler. Table lists the negative regulator jumper options. Positive Voltage Source The MAX748 EV kit features an option to choose which voltage source feeds the positive charge-pump regulator circuit. Jumper JU4 selects the input voltage source for the MAX748 s SUPP pin. Table 4 lists the options.

Output Voltage Selection Boost Switching-Regulator Output Voltages The MAX748 EV kit s boost switching-regulator output is set to +0V by feedback resistors (R, R). To generate s other than +0V (+.7V to +V), select different external voltage-divider resistors (R, R). The ceramic capacitors (C7, C8, C0) are rated to +0V. To set the voltage >+0V, use higher-voltagerated capacitors. Refer to the Output Voltage Selection section in the MAX748 data sheet for instructions on selecting the resistors. The input voltage range will be +.7V to V when selecting other s. Positive Charge-Pump Output Voltages The MAX748 EV kit s positive charge-pump regulator output is set to +5V by feedback resistors (R, R4). To generate s other than +5V, select different external voltage-divider resistors (R, R4). Refer to the Output Voltage Selection section in the MAX748 data sheet for instructions on selecting the resistors. See Table 4 for the jumper selection of input voltage ranges. Check that the capacitor voltage rating is adequate for the configuration. Positive Tripler Charge-Pump Output Voltages The MAX748 EV kit features a positive charge-pump voltage tripler circuit. Three components (C0, C, D4) must be installed and jumper JU modified to utilize the tripler circuit. Capacitors C0 and C should be 0.µF (Taiyo Yuden, UMKBJ04MG recommended) with a voltage rating equal to or greater than the expected output voltage at VPA. Lower cost diodes with higher forward voltage drops can be used for D4, if enough voltage headroom is available. The shorted PC trace across pinholes and must be cut open and a jumper wire installed in pinholes and at jumper JU. Note: VPA will now be the regulated output. To generate a different voltage, select proper voltagedivider resistors (R, R4) while taking into consideration input voltages and jumper settings. Refer to the Output Voltage Selection section in the MAX748 data sheet for instructions on selecting the resistors. See Table 4 for jumper selection of input voltage ranges. Negative Charge-Pump Output Voltages The MAX748 EV kit s negative charge-pump regulator output is set to -5V by feedback resistors (R5, R6). To generate different voltages, select different external voltage-divider resistors (R5, R6) while taking into consideration input voltages and jumper settings. Refer to the Output Voltage Selection section in the MAX748 data sheet for instructions on selecting the resistors. See Table 5 for the jumper selection of input voltage ranges. Negative Doubler Charge-Pump Output Voltages The MAX748 EV kit features a negative charge-pump voltage doubler circuit. Three components (C, C, D5) must be installed and jumper JU modified to utilize the doubler circuit. Capacitors C and C should be 0.µF (Taiyo Yuden UMKBJ04MG recommended) with a voltage rating equal to or greater than the expected at VNA. Lower cost diodes with higher forward voltage drops can be used for D5 if enough voltage headroom is available. The shorted PC trace across pinholes and must be cut open and a jumper wire installed in pinholes and at jumper JU. To generate a different negative, select different external voltage-divider resistors (R5, R6) while taking into consideration input voltages and jumper settings.
