Description

:

The TPS54340 is a 42V, 3.5A, step down regulator with an integrated high side MOSFET. The device survives load dump pulses up to 45 V per ISO 7637.

Current mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load supply current to 146 μA. Shutdown supply current is reduced to 1 μA when the enable pin is pulled low.

Features

1. Current Mode Control DC-DC Converter

2. 92-mΩ High-Side MOSFET

3. High Efficiency at Light Loads with Pulse Skipping Eco-mode

 

4. Low Dropout at Light Loads with Integrated BOOT Recharge FET
