PMP-1307 8.5V Output Test Report Texas Instruments




1 Regulation / Efficiency / Thermal

Regulation vs. load and input: Output is consistently at 8.38V regardless of load. This
is almost 2% below 8.5V. Although reference is +/-1%, voltage sense resistors used in
model are also +/-1% each, allowing overall error to be > 1%.

Efficiency: Vout Iout at battery terminals vs. Vin Iin at Input terminals
For purpose of efficiency calculation of the output under load, I assigned to loaded output
1/6 of the total no load input current.
Input DC volts Input amps Output volts Output amps efficiency
14.00 .431 - .016 8.37 .503 72.4%
