RS2336

700V High Voltage Quasi-Resonant

Fly-back PWM Controller

DESCRIPTION

FEATURES

RS2336 is a highly performance offline 700V high

voltage start up Quasi-Resonant (QR) controller for low

power fly-back converter applications.



Multi-Mode Operation

 Quasi-Resonant (QR) Operation at Normal

 Pulse Frequency Modulation (PFM)

Operation at Light Loading

 Hiccup Mode (HM) Operation at No Loading

700V high voltage start up

Low standby power（<0.15W）

40KHz Minimum Frequency Limit at QR Mode

130KHz Maximum Frequency Limit

Maximum On Time Limit

Maximum and Minimum OFF time Limit

Built-in Leading Edge Blanking

Programmable Soft-start

RS2336 features multiple modes for controlling power

conversion that are designed to achieve maximum

efficient across a wide range of loads. At normal load

condition, it operates in QR mode with minimum drain

voltage switching. It operates in PFM mode for high

power conversion efficiency at light load condition. When

the loading is very small RS2336 operates in Hiccup

Mode to minimize the switching loss. As a result, lower

standby power consumption and higher conversion

efficiency is achieved.



External Latch Triggering

RS2336 offers power on programmable soft-start control

and ensures safe operation with complete protections

against all the fault conditions. Built-in protections

circuitry includes Cycle-by-Cycle current limiting, peak

current protection, OTP，OLP, Output OVP,VCC OVP,

 Rich Protections For System Reliability

including

 VCC Under Voltage Lockout with Hysteresis

(UVLO)

 Cycle-by-Cycle Current Limiting and Peak

Current Protection (OCP)

 Programmable Output Over Voltage

Protection (OVP)

VCC clamp and UVLO, etc.

 Over Loading Protection (OLP)

 Over Temperature Protection (OTP)

 VCC Over Voltage Protection

 VCC Clamp

APPLICATIONS

Offline AC/DC Fly-back Converter for

Power Adapter and Open-frame SMPS

NB/DVD/Portable DVD Power Supplies

LCD Monitor/TV/PC/Set-Top Box Power Supplies

LED power



RoHS Compliant and 100% Lead (Pb)-Free
