Product details

Description

The LR5920 is a current mode PWM switching power supply controller that specifically designed for AC/DC converter with high perfo rmance versus cost ratio.It provides continuo us output power up to 12W in the bro ad voltage range o f 8 5V 265V.Its o ptimized and highly reaso nable circuit design has made it po ssible to minimize the total cost of the pro duct.

Features

¦ Built-in 750V high voltage power switching tube with minimal external parts count ¦ ¦ ¦ ¦ ¦ ¦ ¦ Latched P WM and pulse - by - pulse current limiting inspection Reduced frequency at low o utput with standby po wer consumption below 0.25W Built-in slope and feedback compensation function Separate upper limit current inspectio n co ntroller to handle timely flyback circuit topology to constitute simp le AC/DC converter. The internal initiating circuit of 5920 has been designed with a uniq ue.
