H970 - Switching Power Controller IC

Download the H970 datasheet PDF. This datasheet also covers the H970-Hi variant, as both devices belong to the same switching power controller ic family and are provided as variant models within a single manufacturer datasheet.

General Description

H970 is a high performance current mode PWM controller.

It’s specifically designed for AC/DC adapter, providing as high as 12W continuous power output in a wide input voltage range from 85V AC to 265V AC.

Key Features

  • ․ Built-in 700 V High Voltage Power Transistor and Few Peripheral Components ․ Latching PWM for Cycle-By-Cycle Current Limiting ․ The Stand-by Power Dissipation Be Less Than 0.3W. ․ Built-in Slope and Feedback Compensation Function ․ Independent Up-limit Current circuit Deals with the Over-load and Over Output Current ․ During the Off-state of the Power TR, Reversed Bias Voltage of the Emit Improves its Safety. ․Built-in Temperature Compensation to the Current Sensor Resistor, Improving the Pre.

HI-SINCERITY MICROELECTRONICS CORP. Spec. No. : IC200908 Issued Date : 2009.05.27 Revised Date : 2009.12.08 Page No. : 1/14 H970 Switching Power Controller IC General Description H970 is a high performance current mode PWM controller. It’s specifically designed for AC/DC adapter, providing as high as 12W continuous power output in a wide input voltage range from 85V AC to 265V AC. The peak Package Type : DIP-8 Package Code : P Fig.1 output power can reach as high as 18W.The controller can be typically used in fly-back circuit topology, formed a simplicity AC/DC adapter. The distinctively start-up circuit, by using bootstrap circuit and the amplified of power transistors, significantly decreases the power dissipation of the start-up resistor.
