Datasheet Linear Technology LTC3422EDD#PBF — Ficha de datos

LTC3422
1.5A, 3MHz Synchronous
Step-Up DC/DC Converter
with Output Disconnect U FEATURES DESCRIPTIO ■ The LTC®3422 is a high efficiency, current mode, fixed
frequency, step-up DC/DC converter with true output
disconnect and inrush current limiting. The part is guaranteed to start up from an input voltage of 1V. The device
includes a 0.20Ω N-channel MOSFET switch and a 0.24Ω
P-channel MOSFET synchronous rectifier. The output
voltage, switching frequency, soft-start time, Burst Mode
threshold and loop compensation are all simply programmed using tiny external passive components. ■
