GENERAL DESCRIPTION
The ML4824 is a controller for power factor corrected,
switched mode power supplies. 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 complies
with IEC1000-2-3 specification. The ML4824 includes
circuits for the implementation of a leading edge, average
current, “boost” type power factor correction and a trailing
edge, pulse width modulator (PWM).

The device is available in two versions; the ML4824-1

(fPWM= fPFC) and the ML4824-2 (fPWM= 2 x fPFC).
Doubling the switching frequency of the PWM allows the
user to design with smaller output components while
maintaining the best operating frequency for the PFC. 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 brown-
out protection. The PWM section can be operated in
current or voltage mode at up to 250kHz and includes a
duty cycle limit to prevent transformer saturation.
FEATURES
Internally synchronized PFC and PWM in one IC
Low total harmonic distortion
Reduces ripple current in the storage capacitor between
the PFC and PWM sections
Average current, continuous boost leading edge PFC
Fast transconductance error amp for voltage loop
High efficiency trailing edge PWM can be configured
for current mode or voltage mode operation
Average line voltage compensation with brownout
control
PFC overvoltage comparator eliminates output
“runaway” due to load removal
Current fed gain modulator for improved noise immunity
Overvoltage protection, UVLO, and soft start

These are genuine FAIRCHILD parts.

They came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however in pristine condition still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee. 

PLEASE NOTE!
