MAX16903 - 1A Mini-Buck Converter

General Description

The MAX16903 is a small, synchronous buck converter with integrated high-side and low-side switches.

The device is designed to deliver 1A with input voltages from +3.5V to +28V while using only 25μA quiescent current at no load.

Voltage quality can be monitored by observing the PGOOD signal.

Key Features

  • Meets Stringent Automotive Quality and Reliability Requirements.
  • +3.5V to +28V Input Voltage Range Allows Operation in “Cold Crank” Conditions.
  • Tolerates Input-Voltage Transients to +42V.
  • Enable-Pin Compatible from +3.3V Logic Level to +42V.
  • 1A Minimum Output Current with Overcurrent Protection.
  • -40°C to +125°C Automotive Temperature Range.
  • AEC-Q100 Qualified.
  • Increased Efficiency and Reduced BOM Cost and Board.

MAX16903 EVALUATION KIT AVAILABLE 2.1MHz, High-Voltage, 1A Mini-Buck Converter General Description The MAX16903 is a small, synchronous buck converter with integrated high-side and low-side switches. The device is designed to deliver 1A with input voltages from +3.5V to +28V while using only 25μA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signal. The MAX16903 can operate in dropout by running at 97% duty cycle, making it ideal for automotive and industrial applications. The MAX16903 operates at a 2.1MHz frequency, allowing for small external components and reduced output ripple. It guarantees no AM band interference.
