General Description

The ML4800 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
IEC1000-3-2 specification. Intended as a BiCMOS version
of the industry-standard ML4824, the ML4800 includes
circuits for the implementation of leading edge, average
current, “boost” type power factor correction and a trailing
edge, pulse width modulator (PWM). It also includes a
TriFault Detect™ function to help ensure that no unsafe
conditions will result from single component failure in the
PFC. Gate-drivers with 1A capabilities minimize the need
for external driver circuits. Low power requirements improve
efficiency and reduce component costs.
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.
