IC S9111A 5V500MA 3W SOP-7

 Description

S9111A is a  high performance constant voltage and constant current control chip (CV/CC) without requiring  opto-coupler and the secondary control circuitry ,using Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies and applicable to the isolation of the flyback type power supply . S9111A built-in high VCBO power triode, is the best choice for the  low  power adapter and charger.

 

Features

  •  1)Built-in high voltage power triode

  •   2)High precision constant pressure constant current characteristics

  •   3)<75 mw standby power consumption to meet US DoE VI

  •   4)The unique output line loss compensation technology

  •   5)Open circuit protection, over voltage protection, short circuit protection

 

Application

Adapter, battery charger, standby power supply,LED drive power supply,Upgrading the best choice - linear power supply and RCC switching power supply
