JW1962BH Datasheet Offline Boost Pfc Cv Regulator

Manufacturer: JoulWatt

Overview: JW1962AH/JW1962BH Parameters Subject to Change Without Notice.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The JW®1962AH/JW1962BH(JW1962XH series) is a constant voltage controller with high voltage accuracy which applies to single stage boost power factor corrected(PFC) applications.

The constant on time control strategy ensures high power factor, and the input voltage detection circuit is not needed, which simplifies the system design and saves the loss.

The critical conduction mode operation reduces the switching losses, improves the EMI performance and increases the efficiency.

Key Features

  • Low quiescent current.
  • High power factor and low THD.
  • Critical conduction mode.
  • High voltage power MOSFET integrated.
  • High reference voltage accuracy.
  • High efficiency over wide operating range.
  • Open feedback protection.
  • Disable function.
  • Pulse by pulse current limit.
  • FB over voltage protection.
  • ISP over voltage protection.
  • Internal over-temperature protection.
  • SOP8 package.
