IR3742 Datasheet | International Rectifier

FEATURES - Single input voltage range from 5V to 21V - Wide input voltage range from 1.0V to 21V with external VCC bias voltage - Integrated MOSFET drivers, Control FET, Synchronous FET with Schottky diode, bootstrap diode and the internal LDO - Enable input with voltage monitoring capability - Logic Level Tri-state PWM input - Thermally pensated Over Current Indicator - Open-drain over temperature and over current fault indication - Under-voltage Lockout of VCC/LDO_Out - Operating temp: -40°C < Tj < 125°C - Package size: 5mm x 6mm PQFN - Ro HS6 pliant, lead-free and halogen-free DESCRIPTION The IR3742 integrated Pow IRstage® is a synchronous buck gate driver IC with co-packed control and synchronous MOSFETs and Schottky diode. It is optimized internally for PCB layout, heat transfer and driver/MOSFET timing. Custom designed gate driver and MOSFET bination enables higher efficiency at lower output voltages required by cutting edge ASIC, FPGA and advanced controller. Up to 1.5MHz switching frequency enables high performance transient response, allowing miniaturization of output inductors, as well as input and output capacitors while maintaining industry leading efficiency. The IR3742’s superior efficiency enables smallest size and lower solution cost. The IR3742 includes an over current indicator and over temperature indicator in the event of a fault condition.
