This xCHIP module houses 2 AA batteries to supply power to other connected xCHIPS. The PB04 makes use of the INA199A2 current sensor and MAX11647 Analog to Digital Converter. These two low-cost precision sensors allows for accurately measuring power usage, battery voltage and current draw.

The PB04 features an AAT1217 which is a high efficiency, synchronous, fixed frequency, step-up converter designed for battery-powered applications. The high 1.2 MHz switching frequency and completely integrated control circuitry maintains excellent regulation, ripple, and transient response throughout the full load range.

Light load mode operation and low quiescent current allow the AAT1217 to maintain high efficiency performance for light load conditions. With a 1.2A peak inductor current limit, the AAT1217 is capable of delivering 400mA from dual AA cells batteries.
