Synchronous DC-DC Converter delivers 96% efficiency at full load.
February 15, 2011 -
Housed in 1.65 x 1.65 mm WLP, Model MAX15053 integrates MOSFETs to minimize EMI and save board space. Miniature, current-mode, step-down regulator operates from fixed 1 MHz switching frequency, which allows for small external passive components and all-ceramic capacitor design. Offering both fixed-PWM and skip-mode operation, MAX15053 is suitable for telecom, networking, and base-station equipment. Device operates from 2.7-5.5 V input voltage and is specified over -40 to +85°C temperature range.

Industry's Smallest 2A Synchronous Buck Integrates MOSFETs for up to 96% Efficiency in a 1.6mm by 1.6mm Package
SUNNYVALE, CA - Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX15053, a current-mode, synchronous DC-DC converter in a tiny 1.65mm x 1.65mm wafer-level package (WLP). This miniature step-down regulator integrates MOSFETs to simplify design, minimize EMI, and save board space while achieving conversion efficiency up to 96% at full load (2A). The MAX15053 operates from a fixed 1MHz switching frequency that allows for small external passive components and an all-ceramic-capacitor design, further minimizing total solution size. A peak-current-mode architecture ensures excellent load regulation while simplifying compensation. Offering both fixed-PWM and skip-mode operation, the MAX15053 is suitable for applications ranging from telecom, networking, and base-station equipment to portable devices such as notebooks.
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 MAX15053 operates from a 2.7V to 5.5V input voltage and provides ±1% output-voltage accuracy over temperature. The device is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Prices start at $1.38 (1000-up, FOB USA).
