概述
Description
TPS62056DGS is TI’s TPS62056 family step-down (buck) regulator in the DGS package. It’s designed for portable, battery-powered electronics and provides efficient voltage reduction from a relatively wide input range to a lower system voltage. The device comes in fixed-output or adjustable versions, and includes an enable pin, soft-start, and protection features (overcurrent and thermal shutdown). Like other TPS620xx parts, it uses a traditional buck architecture that requires external passive components (inductor, capacitors) and, for adjustable versions, a feedback network. The DGS package is compact for space-constrained designs. Typical applications include microcontroller power rails, wearables, sensors, and other handheld or battery-powered devices. For exact electrical specifications, pinout, and recommended external components, consult the TI datasheet and product page.
Features
TPS62056DGS features (concise):
- 600 mA step-down (buck) regulator in an 8-pin DGS package.
- Wide input voltage range (typical 2.5 V to 5.5 V).
- Output voltage adjustable via external feedback (0.8 V to 5.5 V) or fixed options.
- Fixed switching frequency around a few hundred kHz (typical ~600 kHz) for easy filtering.
- High efficiency (low quiescent current; excellent light-load efficiency with automatic skipping).
- Built-in protections: overcurrent/short-circuit protection and thermal shutdown.
- Enable pin for easy shutdown and low-power sleep operation.
- Soft-start to limit inrush and prevent output overshoot.
- Minimal external components (inductor, input/output capacitors, feedback network).
- Suitable for compact, battery-powered or portable applications requiring a small footprint.
Note: For exact electrical specs (input limits, output range, switching frequency, and recommended external components), consult the TPS62056DGS datasheet.
