Y5117 17A DC-DC POL Data Sheet
3.0V to 13.2V Input
0.7V to 3.63V Output
APPENDIX A.
Setup and use of evaluation board to test and
measure operation of
A1. Purpose
This procedure explains the requirements for the
proper handling, tup, and testing of the Y5117P, to
ensure the protection of the device.
A2. Overview
Certain conditions have to be met in order to test the
functionality of this device. The Y5117P data sheet
determines constraints, both temperature and power
limitations involved in the testing and operation of the
unit.
These limitations must not be exceeded.
Prolonged operation at elevated temperature or
elevated power output can result in the failure of the
device.
A3. References
All specifications are referenced against latest
revision of the data sheet.
A4. Procedure
A4.1 Test Equipment
Power supply should be capable of delivering a
minimum of 20A and have the overvoltage protection.
Loads must be 30A capable and operate at voltages
down to 0.5V. Lead length between power supply
and unit under test (UUT) and between UUT and
load must be minimized, <1m is recommended.
Additional input capacitance may be required under
specific conditions.
The amount of capacitance
required is a factor of input impedance, input voltage,
input voltage regulation, and output current.
A4.2 Connection of Test Equipment
Pgnd is the common device ground pin. The input
and output ground connections are connected to this
pin.
