MAX16956 - Mini Buck Converter

Description

The MAX16956 is a small, synchronous buck converter with integrated high-side and low-side switches.

The device is designed to deliver up to 300mA with input voltages from 3.5V to 36V, while using only 1.1µA quiescent current at no load (fixed-output versions).

Features

  • Integration and High-Switching Frequency Saves Space.
  • DC-DC Converter Up to 300mA Capability.
  • Fixed 5V/3.3V or Programmable Output-Voltage Options (1V to 10V).
  • Current-Mode-Control Architecture.
  • 2.1MHz Operating Frequency.
  • Fixed 5.4ms Internal Soft-Start.
  • Spread-Spectrum Frequency Modulation Reduces EMI Emissions.
  • Low IQ Enables Designers to Meet Stringent OEM Module Power-Consumption Requirements.
  • 1.1µA Quiescent Current in S.

MAX16956 EVALUATION KIT AVAILABLE 36V, 300mA, Mini Buck Converter with 1.1µA IQ General Description The MAX16956 is a small, synchronous buck converter with integrated high-side and low-side switches. The device is designed to deliver up to 300mA with input voltages from 3.5V to 36V, while using only 1.1µA quiescent current at no load (fixed-output versions). Voltage quality can be monitored by observing the RESET signal. The device can operate near dropout by running at 97% duty cycle, making it ideal for automotive applications under cold-crank. The device offers fixed-output voltages of 5V and 3.3V, as well as an adjustable version. The adjustable version allows the user to program the output voltage between 1V and 10V by using a resistor-divider. Frequency is fixed at 2.
