MAX637ACSA+T
反相, 开关稳压器, 固定, 2.3V至16.5V输入, -15V, 输出, 50kHz, NSOIC-8
产品概述
The MAX637ACSA+T from Maxim Integrated Products 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 -15V 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. Typical applications include minimum component high efficiency DC to DC converter, portable instruments, battery power conversion, board level DC to DC conversion.
