MB3817 - Switching Regulator Controller

Datasheet Summary

Description

The MB3817 is a pulse width modulator (PWM) type switching regulator controller IC designed for low-voltage and high-speed operation.

This can be used in applications as down-conversion or down/up-conversion (Zeta method).

Features

  • Wide range of operating power supply voltages: 2.5 V to 18 V Built-in high-precision reference voltage generator: 1.5 V ± 2% High speed operation is possible: Max. 500 kHz Wide input voltage range of error amplifier: 0 to VCC.
  • 0.9 V Built-in soft start function Built-in timer/latch-actuated short-circuiting protection circuit Totem-pole type output with adjustable on/off current (for PNP transistor.
