SP6851

Green-Mode Power Switch

DESCRIPTION

APPLICATIONS

The SP6851 is a low cost, low startup current, current

mode PWM controller with green-mode

power-saving operation. Built-in 650V MOSFET

provides simple design for adapter. The integrated

functions include the leading-edge blanking of the

current sensing, internal slope compensation. It

would provide the users a superior AC/DC power

application of higher efficiency, low external

component counts, and lower cost solution for

applications.

AC/DC Switching Power Adaptor

Battery Charger

PC 5V Standby Power.

Open-Frame Switching Power Supply

The SP6851 features more protections or functions

for the following characteristics :

※Add OLP (Over Load Protection) function to

provide better protection performance for fault

conditions like short circuit or over load.

※Modify the OVP (Over Voltage Protection)

mechanism from the cycle-by-cycle mode to the

hiccup mode.

SP6851 is available in DIP-8P package.
