This miniature buck regulator integrates MOSFETs to simplify design, minimize EMI, and save board space, while also achieving up to 96% conversion efficiency at full load (2A). The MAX15053 operates at a fixed switching frequency of 1 MHz, allowing designs with small external passive components to minimize the overall size of the solution. A peak current mode architecture ensures excellent load regulation while simplifying compensation.
Offering both fixed and hopping PWM operation, the MAX15053 is suitable for applications ranging from telecommunications, networking, and base station equipment to portable devices such as notebooks. The MAX15053 operates on a 2.7V to 5.5V power supply.
