Primary-side Regulation PWM Power Controller

Description:

OB2210

integrated current mode

PWM controller for low

power AC/DC charger and

adaptor applications. It

operates in primary-side

sensing and regulation.

Consequently, opto-coupler

and TL431 could be

eliminated.

Applications:

GreenEngine

•

Charger

•

CC/CV Battery Charger

Cell/Cordless Phone

Digital Camera Charger

PDA Charger

Small Power Adapter

Auxiliary Power for PC, TV

etc.

Linear Regulator/RCC

Replacement

I-V Curve

is a highly

Technology for Green Power

Features:

Typical Application:

Primary-side sensing and regulation without TL431 and

opto-coupler

Multi-mode operation for high efficiency

Programmable CV and CC regulation

Adjustable constant current and output power setting

Frequency shuffling and adjustable gate drive greatly

improving EMI

Power on soft-start time (4ms)

“Extended Burst Mode Control” for improved efficiency and

minimum standby design

Built-in leading edge blanking (LEB)

Cycle-by-Cycle current limiting

VDD under voltage lockout with hysteresis (UVLO)

VDD over-voltage shutdown and clamp

Auto-restart in over-voltage condition

Fail-safe protection for open loop fault condition

Available in SOT23-6 packages, RoHS compliant
