IC LP3783B 5V2.4A 12W SOP-7

 Description

LP3783B is a  high performance constant voltage and constant current control chip (CV/CC) without requiring  opto-coupler and the secondary control circuitry. LP3783B is the new constant voltage and constant current control chip by LP making , optimizing the driving and built-in high VCBO power triode. LP3783B adopting unique output line loss compensation technology, can effectively compensate the loss of output current on the output line voltage drop. It is the best choice for the  high efficiency and low loss power adapter and charger.

 

Features

  •     1)Built-in high voltage power triode for 5V / 2 A and 5V/ 2.4 A

  •     2)  Collocation the LP synchronous rectifier,Efficiency is as high as 87% for US DoE VI 

  •     3)The valley opening technology,improving the system efficiency

  •     4)High precision constant voltage and constant current control

  •     5)< 75 mw standby power consumption 

  •     6)The unique output line loss compensation technology

  •     7)Open circuit protection, over voltage protection, short circuit protection, over temperature protection

 

Application

  •  1) Adapters/Chargers  for  Cell/cordless  Phones, PDAs, MP3 and Other Portable Devices

  •  2) LED drive power supply

  •  3) Upgrading the best choice - linear power supply and RCC switching power supply

  •  4) Standby and Auxiliary Power Supplies
