GR8830

Green-Mode PWM Controller below 100mW Standby Power

Features

Description

ꢀ

Current mode PWM control

The GR8830 is a highly-integrated, low startup

current, current mode PWM controller with

Green-mode function. This function enables the

power supply to easily meet even the strictest

power conservation requirements. The integrated

functions also include the leading-edge blanking

Standby power below 100mW solution

Under voltage lockout (UVLO)

Non-audible-noise green-mode control

Programmable switching frequency

Internal leading-edge blanking

Internal slope compensation

the current sensing, internal slope

Internal soft start

compensation, cycle-by-cycle peak current

limiting, and soft start. OLP, OCP and OVP

provide protection performance for fault conditions.

For protecting the external power MOSFET from

being damaged by supply over voltage, the

GR8830 OUT pin voltage is clamped to about

13V.

Gate output voltage clamp

Jitter and soft driving for reducing EMI

Over-voltage protection (OVP) on VCC pin

Over-load protection (OLP)

Over-current protection (OCP) on CS pin

Over-temperature protection (OTP)

The GR8830 improves the performance and

reduces the cost of power supplies. It is with both

DIP-8 and SOT-26 package.

Applications

ꢀ

Switching AC/DC power adaptor

Battery charger

Open-frame SMPS
