Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS5402DR is a high-efficiency, low-power asynchronous buck DC-DC converter with a wide input voltage range (3.5V to 28V) and a maximum output current of 1.7A. It is housed in an 8-pin SOIC package, suitable for surface mount applications.

TPS5402DR Key Features

Wide input voltage range: 3.5V to 28V

High output current: up to 1.7A

Adjustable output voltage: the output voltage can be adjusted between 0.8V and 26.04V via an external resistor divider

Fixed-frequency control: Switching frequency can be adjusted between 50kHz and 1.1MHz, with frequency spreading to reduce electromagnetic interference (EMI)

Light-load mode: Automatically enters pulse-skipping mode under light loads to reduce power consumption

Protection features: Includes cycle-by-cycle current limiting, overvoltage protection, and short-circuit protection

Operating temperature range: -40°C to 85°C
