Monolithic Power Systems (MPS) EVL28167-A-Q-00A Evaluation Board

Monolithic Power Systems (MPS) EVL28167-A-Q-00A Evaluation Board is intended for the MP28167-A, a high-efficiency, synchronous buck-boost converter with four integrated power switches and an I²C interface. The MP28167-A offers an integrated output voltage scaling and configurable output current limit functions, ideal for USB power delivery (PD) applications. The MP28167-A requires a minimal number of readily available, standard external components and is housed in a QFN-16 (3mm x 3mm) package.

The MPS EVL28167-A-Q-00A Board regulates output voltage across a wide input voltage supply range of 2.8V to 22V.

Features

Configurable output voltage via the FB pin
Wide 2.8V to 22V operating input range
0.08V to 1.637V Reference Voltage (V_REF) range with 0.8mV resolution via the I²C (Default V_REF is 1V)
3A Output current or 4A input current
Four internal, low R_DS(ON) power MOSFETs
Accurate Constant Current (CC) output current limit with internal sensing
500kHz/750kHz Configurable switching frequency
Line drop compensation

Over-Voltage Protection (OVP) with hiccup mode
Short-Circuit Protection (SCP) with hiccup mode
Over-temperature protection
I²C Interface and One-Time Programmable (OTP) non-volatile memory:
- Pulse-Frequency Modulation (PFM) Pulse-Width Modulation (PWM) modes, line drop compensation, soft start, OCP, OVP, etc.
Configurable EN shutdown discharge
Available in a QFN-16 (3mm x 3mm) package
