SP6837

LOW-POWER OFF-LINE PRIMARY SIDE REGULATION CONTROLLER

DESCRIPTION

FEATURES

The SP6837 has the built-in programmable cable

voltage drop compensation function, which

make it flexible to accommodate various cables

with different gauges and lengths.

· Primary Side Control for Eliminating Opto-

coupler and Secondary CV/CC Control Circuitry

· 30mW No-load Input Power

· Programmable Output Cable Voltage Drop

Compensation

· Proprietary CC Tightening Technique to Achieve

Vertical CC Profile

· Compensation for External Component

Temperature Variations

· Flyback Topology in DCM Operation

· Random Frequency Adjustment to Reduce

System EMI

· Built-in Soft Start

· Over Voltage Protection

The SP6837provides accurate constant voltage,

constant current (CV/CC) regulation without

requiring an opto-coupler and secondary control

circuitry. It also eliminates the need of loop

compensation circuitry while maintaining

stability.

The SP6837 achieves excellent regulation and

high average efficiency, yet meets the

requirement for no-load consumption less than

30mW.

· Short Circuit Protection

The SP6837is a high performance AC/DC power

supply controller for battery charger and adapter

applications. The device uses Pulse Frequency

Modulation (PFM) method to build

discontinuous conduction mode (DCM) flyback

power supplies.

· SOIC-8 Package

APPLICATIONS

· Adapter/Chargers for Cell/Cordless Phones,

PDAs, MP3 and Other Portable Apparatus

· LED Driver

· Standby and Auxiliary Power Supplies

The SP6837is available in SOIC-8 package.
