LX7219-01 Evaluation Board

The LX7219/20 are 6A step-down regulators with integrated MOSFETs, packaged in a space-saving 14-lead, 2 mm x 3 mm VQFN, for today's mobile devices. They use an ultra-fast, constant frequency hysteretic control method to minimize external filter components while maintaining excellent regulation. The LX7219/20 reference voltage is programmable from 0.6V to 1.195V through a high-speed (up to 3.4 MHz), bidirectional I2C bus. The LX7219/20 operate from 2.7V to 5.5V and outputs 0.6V to 3.3V. Cycle-by-cycle current limiting protects against overcurrent conditions. Hiccup mode provides protection against heavy overload or short-circuit faults. Thermal protection shuts down the regulator under overtemperature conditions. Overvoltage conditions will immediately shut off the output to protect against permanent damage. The LX7219/20 automatically restart when all faults disappear. This LX7219/20 Evaluation Board is compatible with LX7219-01, LX7219-02 and LX7220. The evaluation board is the same for all devices, but there are small differences between their operation. The default output voltage is 0.8V for LX7219-01, 0.9V for LX7219-02 and 0.95V for LX7220.
