MAX17231 - Synchronous Dual Buck Controller

Download the MAX17231 datasheet PDF. This datasheet also covers the MAX17230 variant, as both devices belong to the same synchronous dual buck controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX17230/MAX17231 offers dual synchronous stepdown DC-DC controllers with integrated MOSFETs and a step-up/boost controller.

They operate over a 3.5V to 36V input voltage range, and down to 2V with the boost controller active.

Key Features

  • Eliminates External Components and Reduces Total Cost.
  • No Schottky-Synchronous Operation for High Efficiency and Reduced Cost.
  • Simple External RC compensation for Stable Operation at Any Output Voltage.
  • All-Ceramic Capacitor Solution: Ultra-Compact Layout.
  • 180° Out-of-Phase Operation Reduces Output Ripple and Enables Cascaded Power Supplies.
  • Reduces Number of DC-DC Controllers to Stock.
  • Fixed Output Voltage with ±1% Accuracy (5V/3.3V) or Ex.

MAX17230/MAX17231 2V–36V, Synchronous Dual Buck Controller with Integrated Boost and 20µA Quiescent Current General Description The MAX17230/MAX17231 offers dual synchronous stepdown DC-DC controllers with integrated MOSFETs and a step-up/boost controller. They operate over a 3.5V to 36V input voltage range, and down to 2V with the boost controller active. The devices can operate in dropout condition by running at 95% duty cycle. The controllers can generate fixed output voltages of 3.3V/5V, along with the capability to program the output voltage between 1V to 10V. These devices use current-mode-control architecture and can be operated in the pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes.
