Design LM5165-Q1
SNVSAJ3B – MARCH 2016 – REVISED FEBRUARY 2017 LM5165-Q1 3-V to 65-V Input, 150-mA Synchronous Buck Converter With Ultra-Low IQ
1 Features 3 Description The LM5165-Q1 device is a compact, easy-to-use, 3V to 65-V, ultra-low IQ synchronous buck converter
with high efficiency over wide input voltage and load
current ranges. With integrated high-side and lowside power MOSFETs, up to 150-mA of output
current can be delivered at either fixed output
voltages of 3.3 V or 5 V or at an adjustable output.
The converter is designed to simplify implementation
while providing options to optimize the performance
for the target application. Pulse Frequency
Modulation (PFM) mode is selected for optimal lightload efficiency or Constant On-Time (COT) control for
nearly constant operating frequency. Both control
schemes do not require loop compensation while
providing excellent line and load transient response
and short PWM on-time for large step-down
conversion ratios. 1 AEC-Q100 Qualified for Automotive Applications
