ISL78263EVAL1Z

ISL78263EVAL1Z is an ISL78263 evaluation board. This board evaluates the dual-converter, synchronous buck-and-boost operation of the ISL78263. The board evaluates converter 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 helps user to work with ISL78263 features such as overcurrent protection, overvoltage and undervoltage protection, and power-good indicators for each channel. Application includes automotive battery supplied applications, in cabin systems, advanced driver assist systems (ADAS), start-stop protected systems (such as head units, clusters, e-Mirrors).

• VIN operating range from 2.1V to 42V, switching frequency range from 200KHz to 2.2MHz
• Selectable continuous conduction mode (CCM) or energy conservation mode (ECM) allowed
• Boost frequency at 1x or 0.2x the buck frequency, dropout 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, VIN-TYP = 12 to 14V, VIN-MIN = 2.1V (typical)
• VIN-MAX is 42V (typical), VOUT is 15V (up to 10A), VBOOST is 10V when activated, fSW is 2.2MHz
