General Description

The IR1175 is a high speed CMOS controller designed to drive N-channel power MOSFETs used as synchronous rectifiers in high current, high frequency forward converters with output voltages equal or below 5VDC.

Schmitt trigger inputs with double pulse suppression allow the controller to operate in noisy environments.

The circuit does not require any ties to the primary side and derives its operating power directly from the secondary.

Key Features

n Provides constant and proper gate drive to power MOSFETs regardless of transformer output n Minimizes loss due to power MOSFET body drain diode conduction n Stand alone operation - no ties to primary side n Schmitt trigger input with double pulse suppression allows operation in noisy environments n High current drive capability - 2A n High speed operation - 2MHz n Adaptable to multiple topologies (such as singleended forward, double-ended forward) Product Summary Vdd IO+/Fmax Max lead time 5V.
