MAX1044ESA

XBLW · Charge Pumps · SOP-8

MAX1044ESA from XBLW, in a SOP-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 BOOST input Oscillator frequency control input that increases internal oscillator frequency by a factor of 6 when connected to V+, or should be left open if using external oscillator.
2 CAP+ passive Negative terminal connection for the internal charge pump capacitor.
3 GND power_in Ground connection point; negative end of accumulator capacitor should be connected to this pin.
4 CAP- passive Positive terminal connection for the internal charge pump capacitor.
5 VOUT power_out Positive voltage output terminal rated for 0V to 9V; positive end of accumulator capacitor should be connected to this pin.
6 LV input Low voltage mode selection input that should be connected to ground when supply voltage is below 3.5V.
7 OSC input Oscillator frequency control input where an external capacitor reduces the internal oscillator frequency.
8 V+ power_in Power supply positive voltage input rated 1.5V to 9.0V; serves as chip substrate connection point.
