Description
The H38867E8AHP is a high performance fixed frequency current mode controller. It is specifically designed for Off-Line and DC To DC converter applications, providing a cost-effective solution with minimal external components. This integrated circuit features a trimmed oscillator for precise duty cycle control. It also includes a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output which is ideally suited for driving a power MOSFET. Protective features such as input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering are also included.
