ISL78229EV1Z: 36V @ 12A, 7.5 ~ 12V in

Summary

The ISL78229EV1Z board demonstrates the 2-phase synchronous boost operation and PMBus™ functionalities of the ISL78229. 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, PMBus functions, etc.

This board has been configured and optimized for the following operating conditions. Refer to “Operating Range” on page 3 for more detailed descriptions. VIN_MIN = 7.5V (or lower, refer to “Operating Range”), VIN_TYP = 12V, VIN_MAX = 30V (typical), VOUT = 36V (typical), IOUT_MAX = 12A (typical), IIN_AVG_MAX = 41.5A (typical), and fSW = 200 kHz.
