tps6205x is a high efficiency synchronous step-down converter from ti, with a maximum output current of 800ma, an operating voltage range of 2.7-10v, an output voltage range of 0.7-6v, support for fixed output voltages of 1.5v, 1.8v, and 3.3v, and synchronization with external clock signals with a maximum frequency of 1.2mhz. it has the characteristics of high efficiency and low static current.
The TPS6205x family (TPS62050, TPS62051, TPS62052, TPS62054, TPS62056) are high‑efficiency synchronous step‑down converters designed for systems powered from 1‑cell or 2‑cell Li‑ion batteries, 3‑cell to 5‑cell NiCd/NiMH, or alkaline sources. They integrate N‑channel and P‑channel MOSFETs, provide synchronous rectification, and support external synchronization up to 1.2 MHz.
The devices are offered in 10‑pin DGS and 10‑pin MSOP packages, operate over a free‑air temperature range of –40 °C to 85 °C, and feature a typical switching frequency of 850 kHz with an efficiency of up to 93 % depending on load conditions.
