DC/DC Converter

Description

The RPMB-3.0 series is a 3A non-isolated SMD switching regulator power module with up to 36V input

voltage. Despite its compact LGA footprint and low profile (12.2x12.2x3.75mm), it offers a full set of

features including adjustable output from 1V up to 24V, on/off control, sense and power good output

signals. With an efficiency of up to 94% which remains nearly constant over a 5% to 100% load range,

the device can operate at ambient temperatures as high as +100°C without forced air cooling. The

package is complete with 6-sided shielding for optimal EMC performance and excellent heat manage-

ment. The fully protected module (UVLO, SCP, OCP, OTP) can drive high capacitive loads of up to 0.2F.
