MAX635AESA+

The MAX635AESA+ is a preset/adjustable output CMOS inverting switching regulator in 8 pin NSOIC package. This inverting switching regulator is designed for minimum component low power DC to DC conversion. The device is preset for -5V output or can also be adjusted to other voltages using two external resistors. Low battery detection circuitry is included on-chip. For low power applications, the device requires a diode, an output filter capacitor and a catch diode. For high power applications an additional MOSFET and driver is required.
