LM61435AASQRJRRQ1 General Description

A standout feature of the LM61435-Q1 is its auto-mode functionality, which enables frequency foldback at light loads. This innovative feature significantly reduces unloaded current consumption to just 7 µA, while maintaining high light load efficiency. The seamless transition between pulse-width modulation (PWM) and pulse frequency modulation (PFM) modes, coupled with low MOSFET ON resistances and an external bias input, ensure exceptional efficiency across the entire load range

Key Features

Automotive-grade reliability
Efficient power conversion
Compact Hotrod package
Fault-tolerant operation
Industry-standard pinout
Robust against noise and vibration
