CM6824

L^OWS^TART-U^PC^URRENTPFC/PWM C^ONTROLLERC^OMBO

GENERAL DESCRIPTION

FEATURES

The CM6824 is a controller for power factor corrected,

switched mode power suppliers. Power Factor Correction

Patent Filed #5,565,761, #5,747,977, #5,742,151,

#5,804,950, #5,798,635

(PFC) allows the use of smaller, lower cost bulk capacitors, ꢀ

reduces power line loading and stress on the switching ꢀ

FETs, and results in a power supply that fully compiles with ꢀ

Pin to pin compatible with ML4800 and FAN6800/1

Additional folded-back current limit for PWM section.

23V Bi-CMOS process

IEC-1000-3-2 specifications. Intended as a BiCMOS

version of the industry-standard ML4824, CM6824 includes ꢀ

circuits for the implementation of leading edge, average

ꢀ

VIN OK guaranteed turn on PWM at 2.5V instead of 1.5V

Internally synchronized leading edge PFC and trailing edge

PWM in one IC

current, “boost” type power factor correction and a trailing ꢀ

edge, pulse width modulator (PWM). Gate-driver with 1A

capabilities minimizes the need for external driver circuits. ꢀ

Low power requirements improve efficiency and reduce ꢀ

Slew rate enhanced transconductance error amplifier for

ultra-fast PFC response

Low start-up current (100µA typ.)

Low operating current (3.0mA type.)

component costs.

ꢀ

Low total harmonic distortion, high PF

Reduces ripple current in the storage capacitor between the

PFC and PWM sections

ꢀ

An over-voltage comparator shuts down the PFC section in

the event of a sudden decrease in load. The PFC section ꢀ

also includes peak current limiting and input voltage

Average current, continuous or discontinuous boost leading

edge PFC

brownout protection. The PWM section can be operated in ꢀ

current or voltage mode, at up to 250kHz, and includes an ꢀ

accurate 50% duty cycle limit to prevent transformer

VCC OVP Comparator, Low Power Detect Comparator

PWM configurable for current mode or voltage mode
