The desired load-current level is set via the serial port with two 6-bit linear DACs in conjunction with a reference voltage. Internal circuit protection includes short-to-ground, shorted load, thermal shutdown with hysteresis, and crossover current protection.

The A is supplied in a thin profile 1. Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation. Product is under characterization.

What is the function of the MUX pin? When using external diodes, synchronous rectification should be disabled to achieve maximum results. V REG – This should be decoupled with a 0. Are there recommended setup functions for Word 0 and Word 1?
