MPS EVBL2166-D-00A Quick Start Manual

DESCRIPTION
The EVBL2166-D-00A is an evaluation board
for the MP/MPQ2166 with MPS power inductor
stuffed.
MP/MPQ2166 is an internally compensated,
dual, PWM, synchronous, step-down regulator,
which operates from a 2.7V to 6V input and
generates an output voltage as low as 0.6V. It
can be configured as a 2A/2A or 3A/1A output
current regulator and is ideal for powering
portable equipment that runs on a single-cell
lithium-ion (Li+) battery due to a low 60µA
quiescent current.
The MP2166/MPQ2166 integrates dual, 55mΩ,
high-side switches and 20mΩ synchronous
rectifiers for high efficiency without an external
Schottky diode. The MP2166/MPQ2166 has
peak-current-mode
compensation and is capable of low dropout
configurations. Both channels can operate at
100% duty cycle.
Full protection features include cycle-by-cycle
current limit and thermal shutdown.
The EVBL2166-D-00A is assembled and tested
with QFN-18 (2mmX3mm) package.
