IC LP3773A 5V500MA 3W SOP-7

 Description

LP3773C 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 . LP3773C built-in high VCBO power triode, is the best choice for the  low  power adapter and charger.  LP3773A/C adopting unique output line loss compensation technology, can effectively compensate the loss of output current on the output line voltage drop by adjusting the FB partial pressure resistance tolerance.


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
