ADP3120AJCPZ-RL

Gate Driver Overview

The ADP3120AJCPZ-RL is a dual MOSFET gate driver manufactured by onsemi, designed for synchronous buck converter applications. It integrates high-side and low-side drivers capable of driving a 3000 pF load with a 45 ns propagation delay and 25 ns transition time. The device operates within a supply voltage range of 4.6 V to 13.2 V and supports output voltages up to 35 V. It features an adaptive non-overlap circuit to prevent cross-conduction and includes undervoltage lockout and thermal shutdown protection.

Gate Driver Feature Summary

• Integrates high-side and low-side gate drivers optimized for synchronous buck topologies
• Includes internal adaptive non-overlap circuitry to eliminate simultaneous conduction losses
• Provides output disable functionality via logic-level control for safe system shutdown

Gate Driver Applications

• Multiphase desktop CPU power supplies
• Single-supply synchronous buck converters
• VRM designs requiring anti-cross conduction protection

Gate Driver Procurement Notes

Verify component authenticity through authorized distributors as the part is marked end-of-life. Confirm package integrity upon receipt, as LFCSP components are sensitive to moisture and physical stress. Ensure storage conditions meet JEDDEC standards to prevent lead oxidation before reflow soldering.

Gate Driver Selection Notes

Select this driver for single-phase or multiphase VRM designs where compact integration is required. It eliminates external bootstrap diodes and resistors, simplifying layout. Suitable for systems needing precise timing control between high-side and low-side switching events without complex external timing components.

Gate Driver Part Context

This component belongs to the ADP3120 family of dual bootstrapped MOSFET drivers. It shares functional similarities with other ON Semiconductor gate drivers but is specifically tuned for CPU voltage regulator modules. The 'JCPZ' suffix indicates the specific LFCSP package variant used in this reel configuration.

Gate Driver Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official obsolescence notices for recommended alternatives or contact the manufacturer directly for lifecycle management options.
