Overview
Description
The ISL78263EVAL1Z evaluation board is used to evaluate the dual-converter, synchronous buck-and-boost operation of the ISL78263 controller. The board evaluates Channel 1, a synchronous buck operation that provides a system rail voltage, and Channel 2, a boost converter that is activated to support automotive cold crank applications. In addition, the ISL78263EVAL1Z enables evaluation of ISL78263 features such as overcurrent protection, overvoltage and under-voltage protection, and power-good indicators for each channel.
Features
- VIN operating range: 2.1V to 42V
- Selectable continuous conduction mode (CCM) or energy conservation mode (ECM) allowed
- Low quiescent current in ECM mode: 6μA typical, buck channel
- Switching frequency: 200kHz to 2.2MHz
- Boost frequency at 1x or 0.2x the buck frequency
- Drop-out mode (buck) for high duty-cycle operation
- 25ns on-times for low duty cycle operation
- External synchronization input
- Programmable spread spectrum clocking
- 2A sourcing/3A sinking MOSFET drivers
- Boot UVLO and programmable boot refresh time
- Extensive protection mechanisms for OV/UV/OC/OT
- Monitoring test points for key signals
Applications
- Automotive battery supplied applications
- In cabin systems
- Advanced Driver Assist Systems (ADAS)
- Start-stop protected systems (such as head units, clusters, e-Mirrors)
