TPS54302DDCT Description

The TPS54302DDCT is a 3-A synchronous buck converter with a 4.5-V to 28-V input voltage range. To reduce component count, the device has two integrated switching FETs, internal loop correction, and a 5-ms internal soft start.

TPS54302DDCT Features

• Wide input voltage range of 4.5 to 28 volts

• 3-A constant output current with integrated 85-m and 40-m MOSFETs

• Low shutdown current of 2 amps, quiescent current of 45 amps

• Internal soft start of 5 milliseconds

• Switching frequency is fixed at 400 kHz.

• To decrease EMI, use a frequency spread spectrum.

• Pulse skip in advanced Eco-modeTM
