2. Specification
2.1 Electrical Specification
2.1.1 Input
DC 7V ~ 30V (36Vpeak), 2A max.
2.1.2 Output (2* USB-A connector)
DC 5.15V ±0.1V, 2A max. (at Vin ≥ DC 6.5V)
2.1.3 Efficiency
The DC-DC converter efficiency is 82% typically at maximum output load and
rated input Voltage range.
2.1.4 Output Ripple & Noise
The output ripple & noise is less than 150mVp-p.
Measurement shall be made with an oscilloscope with 20MHz bandwidth.
Outputs should be bypassed at the connector with a 0.1uF Ceramic disk capacitor
and 47uF electrolytic capacitor.
2.1.5 Reverse input voltage protection
The DC-DC converter is applied to the reverse voltage will not be damaged
even.
2.1.6 UVLO (Under voltage lock out)
The input voltage is less than 8.6V DC-DC converter operates at a 2Cell mode,
8.6V or greater to 3Cell mode works. The setting of Mode is done automatically.
DC-DC converter input voltage is below the UVLO off voltage when the output
is off, the input voltage is above UVLO on voltage, the output is turned on.
2.1.7 LED indicator
The DC-DC converter with LED indicator displays the status of the operation,
and during normal operation LED indicator turns on.
