The TPS53355DQPR is a 30-A synchronous switcher with integrated MOSFETs that operate in D-CAPTM mode. It's made for ease of use, a small number of external components, and space-saving power systems. This device has integrated 5-m/2-m MOSFETs, a 1 percent 0.6-V reference, and an integrated boost switch. 1.5-V to 15-V wide conversion input voltage range, very low external component count, DCAPTM mode control for super quick transient, auto-skip mode operation, internal soft-start control, customizable frequency, and no need for compensation are just a few of the competitive characteristics.
