MAX20002 - 2A/3A Fully Integrated Step-Down Converters

General Description

The MAX20002/MAX20003 are small, synchronous buck converters with integrated high-side and low-side MOSFETs.

Each device is designed to deliver up to 2A/3A with input voltages from 3.5V to 36V, while using only 15µA quiescent current at no load.

Key Features

  • Synchronous DC-DC Converter with Integrated FETs.
  • MAX20002 = 2A.
  • MAX20003 = 3A.
  • 15µA Quiescent Current When in Standby Mode.
  • Small Solution Size Saves Space.
  • 220kHz to 2.2MHz Adjustable Frequency.
  • Programmable 1V to 10V Output for the Buck or Fixed 5V/3.3V Options Available.
  • Fixed 8ms Internal Soft-Start.
  • Fixed Output Voltage with ±2% Output Accuracy (5V/3.3V) or Externally Resistor Adjustable (1V to 10V).

MAX20002/MAX20003 EVALUATION KIT AVAILABLE 36V, 220kHz to 2.2MHz, 2A/3A Fully Integrated Step-Down Converters with 15μA Operating Current General Description The MAX20002/MAX20003 are small, synchronous buck converters with integrated high-side and low-side MOSFETs. Each device is designed to deliver up to 2A/3A with input voltages from 3.5V to 36V, while using only 15µA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signal. The devices can operate in dropout by running at 98% duty cycle, making them ideal for automotive applications. The devices offer fixed output voltages of 5V/3.3V, along with the ability to program the output voltage between 1V to 10V. Frequency can be programmed using a resistor to ground on the FOSC pin from 220kHz to 2.2MHz.
