CHL8505
Description
The CHL8505 MOSFET is a high‐efficiency gate driver which can switch both high‐side and low‐side N‐channel external MOSFETs in a synchronous buck converter. It is intended for use with IR Digital PWM controllers to provide a total voltage regulator (VR) solution for today’s advanced computing applications.
Key Features
- Ideal for Server Memory applications using +5V
- Fixed 5V Gate Drive
- Large drivers designed to drive 3nF in < 15ns with +5V drive
- Low‐side driver - 2A source/4A sink
- High‐side driver - 2A source/2A sink
- Transitions times & Propagation delays < 15ns
- Integrated bootstrap diode
- Capable of high switching frequencies from 200kHz up to greater than 1MHz
- Compatible with IR’s patented Active Tri‐Level (ATL) PWM for fastest response to transient overshoot
- Non‐overlap and under voltage protection
