IR3537
FEATURES
- Drives both high‐side and low‐side MOSFETs in a synchronous buck configuration
- Large drivers designed to drive 6n F 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 o patible with IR controller VGD feature
- Integrated bootstrap diode o Reduces external ponent count
- Capable of high switching frequencies from 200k Hz up to 1MHz
- Configurable PWM modes of operation o IR Active Tri‐Level (ATL), disables both MOSFETs in 30ns with no hold‐off time o Generic Tri‐State PWM with hold‐off
- Adaptive non‐overlap protection minimizes diode conduction time
- Input supply under voltage protection
- Thermally enhanced 10‐pin DFN package
- Lead free Ro HS pliant package, MSL level 1
