MAX16963 - Low-Voltage Step-Down DC-DC Converter

Description

The MAX16963 is a high-efficiency, dual synchronous step-down converter that operates with a 2.7V to 5.5V input voltage range and provides a 0.8V to 3.6V output voltage range.

The device delivers up to 1.5A of load current per output.

Features

  • a 2.2MHz fixed-frequency PWM mode for better noise immunity and load transient response, and a skip mode for increased efficiency during light-load operation. The 2.2MHz frequency operation allows for an all-ceramic capacitor design and small-size external components. An optional spread-spectrum frequency modulation minimizes radiated electromagnetic emissions due to the switching frequency. On-board low RDSON switches help minimize efficiency losses at heavy loads and reduce critical/parasitic.

MAX16963 Dual 2.2MHz, Low-Voltage Step-Down DC-DC Converter General Description The MAX16963 is a high-efficiency, dual synchronous step-down converter that operates with a 2.7V to 5.5V input voltage range and provides a 0.8V to 3.6V output voltage range. The device delivers up to 1.5A of load current per output. The low input/output voltage range and the ability to provide high output currents make this device ideal for on-board point-of-load and postregulation applications. The device achieves Q3% output error over load, line, and temperature ranges. The device features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load transient response, and a skip mode for increased efficiency during light-load operation. The 2.
