SGM41285 - Step-Up Converter and Current Monitor

Datasheet Summary

Description

SGM41285 constant frequency pulse width modulating (PWM) step-up DC/DC converter

Features

  • an internal switch and a high-side current monitor with high speed adjustable current limiting. This device is capable of generating output voltages up to 70V and providing current monitoring up to 4mA. The SGM41285 operates from 2.8V to 5.5V. The constant frequency (850kHz) current mode PWM architecture provides low noise output voltage that is easy to filter. A high voltage internal power MOSFET allows this device to boost output voltages up to 70V. Internal soft-start circuitry limits the inp.

SGM41285 70V, 300mW Step-Up Converter and Current Monitor for APD Bias Applications GENERAL DESCRIPTION SGM41285 constant frequency pulse width modulating (PWM) step-up DC/DC converter features an internal switch and a high-side current monitor with high speed adjustable current limiting. This device is capable of generating output voltages up to 70V and providing current monitoring up to 4mA. The SGM41285 operates from 2.8V to 5.5V. The constant frequency (850kHz) current mode PWM architecture provides low noise output voltage that is easy to filter. A high voltage internal power MOSFET allows this device to boost output voltages up to 70V. Internal soft-start circuitry limits the input current when the boost converter starts. The SGM41285 features a shutdown mode to save power.
