LM25145 Product details

Description

The LM25145 42-V synchronous buck controller is designed to regulate from a high input voltage source or from an input rail subject to high voltage transients, minimizing the need for external surge suppression components.

Features

1 Versatile Synchronous Buck DC-DC Controller.
Wide Input Voltage Range of 6 V to 42 V.
Adjustable Output Voltage From 0.8 V to 40 V.
Meets EN55022 / CISPR 22 EMI Standards.
Lossless RDS(on) or Shunt Current Sensing.
Switching Frequency From 100 kHz to 1 MHz.
SYNC In and SYNC Out Capability.
40-ns Minimum On-Time for High VIN / VOUT Ratio.
140-ns Minimum Off-Time for Low Dropout.
0.8-V Reference With ±1% Fe.
