SD686X

CURRENT MODE PWM+PFM CONTROLLER WITH BUILT•IN HIGH VOLTAGE

MOSFET

DESCRIPTION

SD686X is current mode PWM+PFM controller with built•in high•

voltage MOSFET used for SWPS,with low standby power and low

start current for power switch. In standby mode, therccuiit enters

burst mode to reduce the standby power dissipatioTn.he switch

frequency is 25~67KHz with jitter frequency for low EMI.

Built•in peak current compensation circuimt akes the limit outpu

power stable even with different input AC voltage. Loimutitput

power can be adjusted through the resistor. Maximum peak current

DIP•8•300•2.54

compensation during power•on reduces pressure on transformer to

avoid saturation, the peak current compensation will decrease

balance after power•on.

It integrates various protections such as undervoltage lockout,

overvoltage protection, overload protection, lead edge blanking,

primary winding overcurrent protection and thermal shutdown. The

APPLICATIONS

circuit will restart until normal if protection occurs.

* SWPS

FEATURES

* Energy Star 2.0 standard

* Lower start•up current (3mA)

* Various switching frequency following load for the higher

efficiency

* Frequency jitter for low EMI

* Overvoltage, overcurrent, overload and over temperature

protections.

* Adjustable limit output power

* Undervoltage lockout

* Built•in high voltage MOSFET

* Auto restart mode

* Peak current compensation

* Maximum peak current compensation for initialization

* Burst mode

* Cycle by cycle current limit
