Description
The GR8830 is a highly-integrated, low startup
current, current mode PWM controller with
Green-mode function. This function enables the
power supply to easily meet even the strictest
power conservation requirements. The integrated
functions also include the leading-edge blanking
of the current sensing, internal slope
compensation, cycle-by-cycle peak current
limiting, and soft start. OLP, OCP and OVP
provide protection performance for fault conditions.
For protecting the external power MOSFET from
being damaged by supply over voltage, the
GR8830 OUT pin voltage is clamped to about
13V.
The GR8830 improves the performance and
reduces the cost of power supplies. It is with both
DIP-8 and SOT-26 package.
