Description
The CM6800 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 IEC-1000-3-2 specifications. Intended as a
BiCMOS version of the industry-standard ML4824,
CM6800 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.
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.
CM6800 includes an additional folded-back current limit
for PWM section to provide short circuit protection
function.
