tps64200 is a member of the tps6420x family of nonsynchronous step-down controllers that are ideally suited for systems powered from a 5-v or 3.3-v bus or for applications powered from a 1-cell li-ion battery or from a 2- to 4-cell nicd, nimh, or alkaline battery.
The TPS64200 is a nonsynchronous step‑down controller designed for low‑power applications such as DSP supplies, digital cameras, hard‑disk drives, and portable audio players. It operates from a 1.8 V to 6.5 V input range, offers an adjustable output voltage (1.2 V‑6.5 V), up to 100 % duty cycle, and efficiencies up to 95 %.
The datasheet includes ordering information, absolute maximum ratings, recommended operating conditions, electrical characteristics, pin assignments, functional block diagram, typical performance graphs, mechanical package dimensions, and an important notice about warranty and product availability.
