SLVS996D – SEPTEMBER 2009 – REVISED SEPTEMBER 2015 TPS54262-Q1 Automotive 2-A 60-V Step-Down DC-DC Converter With Low I(q) and
Voltage Supervisor
1 Features 3 Description The TPS54262-Q1 device is a 60-V, 2-A step-down
switch-mode power supply with a low-power mode
and a programmable voltage supervisor with an
integrated NMOS switching FET. Integrated input
voltage line feed forward topology improves line
transient regulation of the voltage mode buck
regulator. The regulator has a cycle-by-cycle current
limit. The device also features low-power mode
operation under light-load conditions which reduces
the supply current to 50 ВµA (typical). By pulling the
EN pin low, the supply shutdown current is reduced
to 1 ВµA (typical). 1 Asynchronous Switch Mode Regulator
Qualified for Automotive Applications
3.6-V to 48-V Operating Range, Withstands
Transients up to 60 V …
