5 Getting to know the hardware

5.1 Board overview

The FRDM-PF1550EVM board is an easy-to-use circuit board, allowing the user to

exercise all the functions of the PF1550 power management IC.

The FRDM-KL25Z is mounted to the EVB as an integral component and serves as an

interface between the KITPF1550GUI and the PF1550 PMIC. The FRDM-KL25Z drives

circuitry on the FRDM-PF1550EVM, as well as provides an analog-to-digital convertor

(ADC) to allow real-time monitoring of the PF1550 regulator voltages, and display their

values in the GUI.

5.2 Board features

The board features are as follows:

• PF1550 power management IC

• Integrated FRDM-KL25Z as a communication link between the EVB and a PC

• One 1.0 Amp ELOAD with configurable current

• NTC Thermistor for temperature measurements (necessary for JEITA compliance)
