Description
PT2201 is a highly integrated current mode PWM controller, with the
Features
- of extreme low start up current, low operating current plus green mode operation and built-in protection functions allows the design of SMPS become easier to meet the high performance, high reliability and low standby power requirements. The start-up current is very small typically 3uA so that a large start up resistor can be used in the start-up circuit to minimize standby power. Under the light load or no load conditions the PT2201 automatically decreases PWM frequency and enters burst mode op.
