SLVSDX5 – FEBRUARY 2017 TPS54340B-Q1 4.5-V to 42-V Input, 3.5-A, Step-Down DC-DC Converter With Eco-Mode™
1 Features 3 Description The TPS54340B-Q1 device is a 42-V, 3.5-A, stepdown 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 ОјA. Shutdown supply
current is reduced to 1 ОјA when the enable pin is
pulled low. 1 Qualified for Automotive Applications
