Product Overview

The MAX643ACPA+ is a fixed output 10W CMOS step-up switching regulator in 8 pin DIP package. This regulator is preset to +15V output voltage however it can be set to other levels by adding 2 resistors. Device is designed for minimum component DC-DC converter circuit in 5mW to 10mW range. It is used in uninterruptible board level power supplies, power conditioning for battery systems and portable instruments and communication.
  • Operating voltage range from 2V to 16.5V
  • Oscillator frequency is 50KHz at Vout = +15V
  • Oscillator duty cycle is 50%
  • Supply current of 0.75mA at Vout = +15V
  • Internal reference voltage of 1.31V at TA= +25°C
  • Typical efficiency of 80% (with external MOSFET)
  • Line regulation of 0.08%Vout, operating temperature range from 0°C to 70°C
  • Load regulation of 0.2%Vout
  • On-chip driver for high power external MOSFET
