to 12W or higher. Soft-start reduces current surges during start-up. A high switching frequency (up to 300kHz) and opera.
The MAX1626/MAX1627 step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA to more than 2A. A unique current-limited, pulse-frequency-modulated (PFM) control scheme operates with up to a 100% duty cycle, resulting i.
