1. Guaranteed by bench measurements. Performances verified in applicative conditions. Tested in static load conditions (Iload

= 150 mA at 400 kHz and 2.4 MHz).

2. Digital implementation is guaranteed by scan test.

3. Guaranteed by design.

BUCK2 converter

The voltages are referred to GND and currents are assumed positive, when the current flows into the pin.

8.5 V ≤ VIN12 ≤ 29 V, Tj = -40 °C to 150 °C, unless otherwise specified.

BUCK2 shares the same input as BUCK1.
