LM5116
Overview
The LM5116 is a synchronous buck controller intended for step-down regulator applications from a high voltage or widely varying input supply. The control method is based upon current mode control utilizing an emulated current ramp.
- Emulated peak current mode Wide operating range up to 100V Low IQ sleep mode (<10µA) Drives standard or logic level MOSFETs Robust 2A peak gate drive Free-run or synchronous operation to 1MHz Optional diode emulation mode Programmable output from 1.215V to 80V Precision 1.5% voltage reference Programmable current limit Programmable soft-start Programmable line under-voltage lockout Automatic switch to external bias supply TSSOP-20EP exposed pad Thermal shutd
