SSD153

Overview

SSD153 is a synchronous, high-efficiency, step-up boost converter. It is designed to operate from an wide input voltage range between 2.6V and 20V with up to 15A peak switch current limit. The device adopts adaptive constant off-time and current mode control. The pseudo-constant switching frequency in CCM can be programmed. PFM/USM/PWM light load operation is selected by the MODE pin. It also supports adjustable switching frequencies from 300kHz to 2MHz for different inductor and output capacitor combinations.
