Introduction
The ICW3115 is a high-efficiency synchronous rectification step-down DC-DC converter IC with an input voltage up to 18V. It integrates two NMOSFET power switches with low on-resistance, supporting up to 2A load current. The device operates in PFM mode under light load and in continuous-current quasi-PWM mode under heavy load, with a switching frequency of 500 kHz. The IC employs an adaptive constant on-time control architecture for fast load transient response. Built-in protection features including over-temperature protection, input UVLO, cycle-by-cycle current limiting, and output short-circuit protection enhance overall reliability.
