CHL8510 Key Features
- Drives both high‐side and low‐side MOSFETs in a synchronous buck configuration
- Large drivers designed to drive 6nF server class FETs o Low‐side driver
- 4A source / 6A sink o High‐side driver
- 3A source / 4A sink o Transition times & propagation delays < 20ns
- Independent variable gate drive voltage for both high‐ and low‐side drivers from 4.5V to 13.2V o Improves efficiency
- Integrated bootstrap diode o Reduces external ponent count
- Capable of high switching frequencies from 200kHz up to 1MHz
- Configurable PWM modes of operation o IR Active Tri‐Level (ATL), disables both MOSFETs in 30ns with no hold‐off time
- Adaptive non‐overlap protection minimizes diode conduction time
- Input supply under voltage protection
