Part Overview
Description
The MAX16955 is a current-mode, synchronous PWM step-down controller designed for wide input voltage range (3.5V to 36V) and low quiescent current (50μA at no load). It features adjustable switching frequency (220kHz to 1MHz) and output voltage (1V to 10V). The device operates in fixed-frequency PWM mode and low quiescent current skip mode, and includes protection features such as overcurrent limit, overvoltage, undervoltage, and thermal shutdown with automatic recovery.
Features
Wide input voltage range (3.5V to 36V)
42V input transient tolerance
High duty cycle during undervoltage transients
Adjustable switching frequency (220kHz to 1MHz)
Current-mode control architecture
Adjustable output voltage (1V to 10V) with ±2% accuracy
Three operating modes:
50μA ultra-low quiescent current skip mode
Forced fixed-frequency mode
External frequency synchronization
Lowest BOM count, current-mode control architecture
Power-good output
Enable input compatible from 3.3V logic level to 42V
Current-limit, thermal shutdown, and overvoltage protection
-40°C to 125°C automotive temperature range
Automotive qualified
Applications
Wide input voltage range point of load
