SG6859A

Low-Cost, Green-Mode PWM Controller for Flyback Converters

Features

Description

This highly integrated PWM controller provides several

enhancements designed to meet the low standby-power

needs of low-power SMPS. To minimize standby power

consumption, the proprietary green-mode function

provides off-time modulation to linearly decrease the

switching frequency under light-load conditions. This

green-mode function enables the power supply to meet

even the strictest power conservation requirements.

Green-Mode PWM

Supports the “Blue Angel” Standard

Low Start-up Current: 9μA

Low Operating Current: 3mA

Leading-Edge Blanking

Constant Output Power Limit

Universal Input

Built-in Synchronized Slope Compensation

Current-Mode Operation

Cycle-by-cycle Current Limiting

Under-Voltage Lockout (UVLO)

The BiCMOS fabrication process enables reducing the

start-up current to 9μA and the operating current to

3mA. To further improve power conservation, a large

start-up resistance can be used. Built-in synchronized

slope compensation ensures the stability of peak

current mode control. Proprietary internal compensation

provides a constant output power limit over a universal

AC input range (90V_ACto 264V_AC). Pulse-by-pulse current

limiting ensures safe operation during short-circuits.

Programmable PWM Frequency with Frequency

Hopping

To protect the external power MOSFET from damage by

supply over voltage, the SG6859A’s output driver is

clamped at 17V. SG6859A controllers can be used to

improve the performance and reduce the production

cost of power supplies. The best choice for replacing

linear and RCC-mode power adapters, the SG6859A is

available in 8-pin DIP and 6-pin SOT-26 packages.

Applications

General-purpose switching mode power supplies and

flyback power converters, such as:

Battery chargers for cellular phones, cordless

phones, PDAs, digital cameras, and power tools

Power adapters for ink jet printers, video game

consoles, and portable audio players

Open-frame SMPS for TV/DVD standby and auxiliary

supplies, home appliances, and consumer electronics

Replacements for linear transformers and RCC SMPS
