Description
The highly integrated SG6932 is designed for power
supplies with boost PFC and forward PWM. It requires
very few external components to achieve versatile
protections and compensation. It is available in 16-pin
DIP and SOP packages.
The
proprietary
interleave-switching
feature
synchronizes the PFC and PWM stages and reduces
switching noise. At light load, the switching frequency is
continuously decreased to reduce power consumption.
For PFC stage, the proprietary multi-vector control
scheme provides a fast transient response in a low-
bandwidth PFC loop; in which the overshoot and
undershoot of the PFC voltage are clamped. If the
feedback loop is broken, SG6932 shuts off to prevent
extra-high voltage on output.
For the forward PWM stage, the synchronized slope
compensation ensures the stability of the current loop
under continuous-conduction-mode (CCM) operation.
Hiccup operation during output overloading is
guaranteed. The soft-start and programmable maximum
duty cycle ensure safe operation.
SG6932 provides complete protection functions, such
as brownout protection and RI open/short latch off.
