Synchronous DC-DC Regulators achieve 96% efficiency.
Press Release Summary:
Model MAX15050 employs pulse-skip mode to optimize light-load efficiency, and is suited for use in notebooks and single-cell portable devices, while MAX15051 operates with forced PWM mode, for use in telecom, networking, and base-station applications. Featuring 2 x 2 mm package, both 4 A, 2.9-5.5 V point-of-load converters include MOSFETs as well as enable input and power-good indicator. They operate from fixed 1 MHz switching frequency and operate over -40 to +85°C temperature range.
Original Press Release:
4A, Synchronous DC-DC Regulators with Integrated MOSFETs Achieve 96% Efficiency in 4 sq mm Package
SUNNYVALE, CA - Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX15050/MAX15051, low-voltage (2.9V to 5.5V), 4A, synchronous DC-DC regulators in a 2mm x 2mm wafer-level package (WLP). These tiny step-down regulators integrate MOSFETs to simplify design, minimize EMI, and save board space. Operation from a fixed 1MHz switching frequency further reduces total solution size, allowing all-ceramic-capacitor designs. Offering peak efficiencies up to 96%, these point-of-load converters minimize power losses in applications ranging from portable devices to networking equipment.
The MAX15050 employs a pulse-skip mode to improve light-load efficiency, making it ideal for applications such as notebooks and single-cell portable devices. The MAX15051 operates with a forced PWM mode, allowing it to be used in telecom, networking, and base-station applications.
Other features include an enable input and power-good indicator for power sequencing, adjustable soft-start for controlled turn-on, and the ability to safely start up into a prebiased output.
The MAX15050/MAX15051 provide ±1% output-voltage accuracy over load, line, and temperature, and are fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Prices start at $2.17 (1000-up, FOB USA).
