CM6800A

LOW START-UP CURRENT PFC/PWM CONTROLLER COMBO

GENERAL DESCRIPTION

FEATURES

The CM6800A is a controller for power factor corrected,

switched mode power suppliers. Power Factor Correction

(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

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

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

Pin to pin compatible with ML4800 and FAN6800

Additional folded-back current limit for PWM section.

23V Bi-CMOS process

IEC-1000-3-2 specifications. Intended as

BiCMOS

VIN OK turn on PWM at 2.25V instead of 1.5V(ML4800).

Internally synchronized leading edge PFC and trailing edge

PWM in one IC

version of the industry-standard ML4824, CM6800A

includes circuits for the implementation of leading edge,

average 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 component costs.

Slew rate enhanced transconductance error amplifier for

ultra-fast PFC response

^{Low start-up current (100}μ^{A typ.)}

Low operating current (3.0mA type.)

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

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

saturation.

Average current, continuous or discontinuous boost leading

edge PFC

VCC OVP Comparator, Low Power Detect Comparator

PWM configurable for current mode or voltage mode

operation

Current fed gain modulator for improved noise immunity

Brown-out control, over-voltage protection, UVLO, and soft

start, and Reference OK

CM6800A includes an additional folded-back current limit

for PWM section to provide short circuit protection function.
