RT7736

SmartJitter^TMPWM Flyback Controller

General Description

Features

^Proprietary SmartJitter^TMTechnology

^Reducing EMI Emissions of SMPS

^Output Jittering Ripple Elimination

^No Load Input Power Under 100mW (RT7736G/R/L/E)

^Accurate Over Load Protection

^UVLO 9V/14.5V

The RT7736 series is a high performance enhanced PWM

flyback controller with proprietary SmartJitter^TMtechnology.

The innovative SmartJitter^TMtechnology not only reduces

EMI emissions of SMPS when the system enters burst

switching green mode, but also eliminates output jittering

ripple.

^PRO Pin for External Arbitrary OVP/OTP

^IC ON/OFF Control (RT7736G/R/L)

^BNO Pin for Brown-In/Out (RT7736B/F)

^Soft Driving for EMI Noise Reduction

^Driver Capability : 300mA/−300mA

^High Noise Immunity

The RT7736 is a current mode PWM controller including

built-in slope compensation, internal Leading Edge

Blanking (LEB) and cycle-by-cycle current limit. It provides

excellent green power performance, especially under light

load and no load conditions. It allows for simpler design

and reduces external component count.

 RoHS Compliant and Halogen Free

This controller integrates comprehensive safety protection

functions for robust designs including input Under-Voltage

Lockout (UVLO), Over-Voltage Protection (OVP), Over-

Load Protection (OLP), Secondary Rectifier Short

Protection (SRSP), CS pin open protection and cycle-by-

cycle current limit.

Applications

 SwitchingAC-DCAdaptor

 DVDOpen Frame Power Supply

 Set-Top Box (STB)

 ATX Standby Power

 TV/Monitor Standby Power

 PC Peripherals

The RT7736 is a cost-effective and compact solution for

NB adaptor applications. It is available in the SOT-23-6

package.
