概述
描述
The ISL78227EV1Z board demonstrates the 2-phase synchronous boost operation of the ISL78227 automotive grade (AEC-Q100 Grade 1), 2-phase, 55V synchronous boost controller. It verifies the high efficiency of synchronous boost operation and all the features of the IC including input constant current (CC) control, analog/digital tracking, diode emulation, phase dropping, etc.
特性
- Input/output voltage withstands 55V DC and 60V transients
- Input average constant current (CC) control loop
- PWM and analog track functions
- Forced PWM operation with negative current limiting
- External synchronization
- Selectable continuous conduction mode (CCM), diode emulation (DE) and phase dropping (PH_DROP) modes
- Comprehensive protections
- Selectable hiccup or latch-off fault responses
- Boards can be stacked for parallel operations
- Monitoring test points for key signals
