Description
The GR8836 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 com-
pensation, cycle-by-cycle peak current limiting,
and soft start. OLP, OCP and OVP provide
protection performance for fault conditions. To
protect the external power MOSFET from being
damaged by supply over voltage, the GR8836
OUT pin voltage is clamped to about 18V. The
GR8836 improves the performance and reduces
the cost of power supplies. It is with 8-pin DIP and
6-pin SOT-26 package.
