GENERAL DESCRIPTION
The EV1531DQ-002A Evaluation Board is
designed to demonstrate the capabilities of
MPS’ MP1531 triple output step-up converter
with charge-pumps.
The MP1531 includes a 250KHz fixed-frequency
step-up converter and a positive and negative
linear regulator. The linear regulators are
powered via charge-pumps driven by the step-up
converter switch node.
A single on/off control enables all 3 outputs.
The outputs are internally sequenced at power-
on for ease of use. An internal soft-start
prevents overloading the input source at
startup. Cycle-by-cycle current limit reduces
component stress.
