The TPS6420x are 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. These step-down controllers drive an external P-channel MOSFET allowing design flexibility. To achieve highest efficiency over a wide load current range, this controller uses a minimum on time, minimum off time control scheme and consumes only 20-µA quiescent current. The minimum on time of typically 600 ns (TPS64203) allows the use of small inductors and capacitors. When disabled, the current consumption is reduced to less than 1 µA. The TPS6420x is available in the 6-pin SOT23 (DBV) package and operates over a free air temperature range of –40°C to 85°C.

TPS64202EVM-023 — TPS64202 評估模組 (3.3V @ 2A)

The TPS64202EVM-023 is an evaluation tool for the TPS64202 inductive step-down controller in SOT-23 package which can supply voltages down to 1.2V from a 1.8-V to 6.5-V input. The TPS64202EVM-023 uses a TPS64202 adjustable output step-down controller and the appropriate external components to (...)
