MAX660MX

Texas Instruments · DC-DC Converters · SOIC-8

MAX660MX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FC input Frequency control logic input; select 10 kHz (open) or 80 kHz (tied to V+) oscillator frequency; no effect when OSC is externally driven.
2 CAP+ passive Positive terminal connection for external charge-pump capacitor; use low-ESR capacitor to minimize output impedance and maximize conversion efficiency.
3 GND power_in Ground reference in voltage inverter mode or positive voltage supply input in voltage doubler mode; bypass with low-ESR capacitor placed close to device.
4 CAP- passive Negative terminal connection for external charge-pump capacitor; use low-ESR capacitor to minimize output impedance and maximize conversion efficiency.
5 OUT power_out Negative voltage output in inverter mode (100 mA maximum continuous output current, 6.5 Ω typical output impedance) or positive supply return in doubler mode.
6 LV input Low-voltage mode control input; tie to GND when input voltage is below 3.5 V or when OSC is externally driven; tie to OUT in doubler mode.
7 OSC input Oscillator frequency control input with internal 15-pF capacitor; external capacitor slows oscillator or external clock up to 150 kHz can drive oscillator in inverter mode only.
8 V+ power_in Power supply positive voltage input at 1.5-5.5 V (inverter LV = GND), 3.5-5.5 V (inverter LV = open), or 2.5-5.5 V (doubler mode); functions as positive voltage output in doubler mode.
