Current Mode PWM Controller

General Description

SDC4569A

SDC4569A is a highly integrated current mode PWM

control IC optimized for high performance, low standby

power and cost effective offline flyback converter

applications in sub 60W range.



Frequency shuffling technology for improved EMC

performance



Audio noise free operation

Extended burst mode control for improved efficiency

and minimum standby power design

External programmable pwm switching

Internal synchronized slope compensation

Low VDD startup current and low operating current

Leading edge blanking on current sense input

Good protection coverage with auto self-recovery

(UVLO/OVP/OCP/OLP)

The internal slope compensation improves system large

signal stability and reduces the possible subharmonic

oscillation at high PWM duty cycle output. Leading-edge

blanking on current sense(CS) input removes the signal

glitch due to snubber circuit diode reverse recovery and

thus greatly reduces the external component count and

system cost in the design.



Package: SOP-8

SDC4569A offers complete protection coverage with

automatic self-recovery feature including cycle-by-cycle

current limiting (OCP), over load protection (OLP), VDD

over voltage clamp and under voltage lockout (UVLO). The

gate drive output is clamped to maximum 12V to protect

the power MOSFET.

Applications



Battery charger

Power adaptor

Set-top box power supplies
