MAX15003 Evaluation Kit
Evluates:MAX1503
General Description
Features
The MAX15003 evaluation kit (EV kit) is a fully assembled
and tested surface-mount printed-circuit board (PCB)
that demonstrates the capabilities of the MAX15003 IC.
The MAX15003 IC is a high-performance triple-output
synchronous buck controller, capable of delivering up to
10A per output with tracking and sequencing capability.
The EV kit requires a DC input-voltage range of 6V to
14V (12V typ) for normal operation.
♦ Triple-Output Power Supply
VOUT1 (3.3V, 3A)
VOUT2 (2.5V, 4A)
VOUT3 (1.2V, 10A)
♦ 600kHz PWM Switching
♦ Programmable Switching Frequency Up to 2.2MHz
♦ External Frequency Synchronization
♦ Selectable Tracking or Sequencing Operation Mode
♦ Selectable Phase Operation Mode
The EV kit outputs are configured for 3.3V, 2.5V, and
1.2V, and provide 3A, 4A, and 10A, respectively. The
MAX15003 IC switching frequency is programmed to
600kHz or can be synchronized to an external clock sig-
nal with a frequency of up to 2.2MHz. The phase-and-
tracking/sequencing operation modes are configurable.
The PGOOD1, PGOOD2, PGOOD3, and RESET logic
signal output pads are provided for circuit monitoring.
♦ Individual PGOOD and RESET Signal Outputs
♦ Fully Assembled and Tested
