MAX15022 Evaluation Kit
Evluates:MAX1502
General Description
Features
The MAX15022 evaluation kit (EV kit) circuit demon-
strates the MAX15022 IC, which integrates two high-
performance PWM switching step-down regulators and
two low-dropout (LDO) controllers. Each controller and
regulator features independent enable controls for
power-up sequence operation. The EV kit is designed
to operate from a single 4.5V to 5.5V DC power supply.
o 4.5V to 5.5V Input Range
o Regulator Outputs
3.3V at 4A
1.5V at 2A
o 2MHz Switching Frequency
o LDO Outputs
The synchronous step-down outputs provide 3.3V/4A
and 1.5V/2A, and can be configured for power-up
sequencing or tracking operation. The converter
switching frequency is set to 2MHz and operates 180°
out-of-phase, reducing input voltage ripple and total
RMS input ripple current. The LDO outputs provide
2.5V and 1.2V, at up to 500mA each. Each LDO con-
troller is powered from either the input power source or
one of the regulator outputs.
2.5V (Up to 500mA)
1.2V (Up to 500mA)
o Independent Enable Inputs for All Outputs
o Configurable Power-Up Sequencing for Outputs
o Configurable Power-Up Tracking for Regulators
(VOUT1, VOUT2)
o Thermal Shutdown and Hiccup-Mode Short-
Circuit Protection
Ordering Information
o Fully Assembled and Tested
