IC LP3783BM SOP-7

 Description

LP3783BM is a  high performance constant voltage and constant current control chip (CV/CC) without requiring  opto-coupler and the secondary control circuitry. LP3783BM is the newest constant voltage and constant current control chip by LP making, optimizing the dynamic characteristics and EMI. LP3783BM 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 850V high voltage triode

  •     2)The unique Frequency Jitter technology, optimizing EMI

  •     3)High performance dynamic characteristics

  •     4)Sloping current drive,optimizing the average efficiency

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

  •     6)High precision constant voltage and constant current control

  •     7)< 75 mw standby power consumption to meet US DoE VI

  •     8)The unique output line loss compensation technology

  •     9)Hiccup function

  •     10)FB resistance open or short protection

  •     11)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
