ADP3120AJRZ

The ADP3120AJRZ from On Semiconductor is a dual bootstrapped MOSFET gate driver optimized for driving both high-side and low-side power MOSFETs in synchronous buck converters. This device features a wide operating voltage range from 4.6V to 13.2V, allowing for optimized efficiency. It includes internal adaptive nonoverlap circuitry to reduce switching losses by preventing simultaneous conduction.

Key electrical specifications include a driven configuration of half-bridge, supporting N-channel MOSFETs, with two drivers capable of synchronous operation. The input type supports both inverting and non-inverting signals. The high-side voltage can reach up to 35V. The device offers a propagation delay of 45 ns and a transition time of 25 ns when driving a 3000 pF load.

Packaged in an 8-SOIC form factor with a width of 3.90mm, the ADP3120AJRZ is designed for surface mounting. It operates within a junction temperature range of -20°C to 150°C. The device also includes features like output disable and undervoltage lockout for robust operation.

This component is suitable for applications such as multiphase desktop CPU supplies and single-supply synchronous buck converters. It is noted as Pb-Free and meets RoHS3 compliance standards.
