Dual-rail power for automotive ECUs
The output voltages are programmable via external resistors, with fixed options of 1.575 V, 1.9 V, and 3.3 V available.
Switching frequency and inductor selection
The 2.3 MHz switching frequency lets you use a 1 µH to 2.2 µH inductor, keeping the total solution footprint under 30 mm². At this frequency the ripple current stays within 30 % of the DC output at full load, so the output capacitor can be a single 10 µF ceramic.
Automotive temperature grade and package
The exposed paddle is tied to the ground plane for both thermal and electrical return.
