Description and Introduction

Geyserville-Enabled DC/DC Converter Controller for Mobile CPUs The ADP3421 is a dual N-channel MOSFET driver manufactured by Analog Devices. It is designed to drive two N-channel power MOSFETs in a synchronous rectified buck converter topology. Key specifications include:

- **Supply Voltage (VCC):** 4.5V to 5.5V
- **Output Current (Source/Sink):** 2A (peak)
- **Propagation Delay (tPD):** 25ns (typical)
- **Rise/Fall Time (10% to 90%):** 10ns (typical)
- **Operating Temperature Range:** -40°C to +85°C
- **Package:** 8-lead SOIC

The ADP3421 is optimized for high-frequency switching applications and features adaptive shoot-through protection to prevent simultaneous conduction of the high-side and low-side MOSFETs. It also includes undervoltage lockout (UVLO) protection to ensure proper operation under low supply voltage conditions.
