产品概述

The MAX634CPA+ is a CMOS micro power inverting switching regulator in 8 pin DIP package. This DC-DC regulator is designed for simple, efficient, inverting DC-DC converter circuits. Switching regulator provide all control and power handling functions, a 1.25V bandgap reference, an oscillator, a comparator for output voltage regulation and a 525mA P-channel output MOSFET. A second comparator is also provided for convenient low battery detection. Operating current is typically 100µA and is nearly independent of output switch current and duty cycle thus ensuring high efficiency even in low power battery operated systems. Operating in inverting configuration, IC can convert a positive input voltage in the range of +3V to 16.5V to any negative output voltage up to -20V. It is used in high efficiency battery powered DC-DC converters, board level, local power supply generation and regulated voltage inverters.
  • Supply voltage range from 2.3V to 16.5V
  • Operating temperature range from 0°C to 70°C
  • Maximum supply current of 150µA at Vs=4V
  • Output voltage range from -5.2V to -4.8V at Vout nom = -5V
  • Maximum line regulation of 2%Vout at Vout nom = -5V
  • Maximum load regulation of 0.4%Vout at Vout nom = -5V
  • Reference voltage of 1.25V, switch current of 150mA at pin 5 = 5V
  • Efficiency of 80%
