Input operating voltage 2.9V to 32 VDC
Output voltage 5V to 38VDC
  Note: the output voltage must be higher than the input voltage
Note: the output voltage is adjustable by a trim pot from the top of the package. We will adjust it to 5V before shipping unless you request a specific voltage when ordering.
Maximum output current 0.1A to 4A depending on the input and output voltages, see below.
Undervoltage lockout 2.6V ± 0.1V
Temperature Range -35C to +60C
Electrostatic immunity Human body model ±2000V
Operating temperature range -20°C to +75°C (-4°F to 167°F)
Overcurrent protected Pulse by pulse overcurrent protected
Overcurrent protection Yes, by reverse biased diode across the input terminals. A fuse in the input line is required to prevent damage.
Thermal protected Automatic restart with 15°C hysterisis
Size 104x52x13mm (4x2x0.5 inches) including flange
Weight 2.4 oz, 68g

Maximum output current can be determined with the following formual
Imax = [Vin/(Vout+0.5)] * 4.2Amps

Where Vin is the minimum expected input voltage in the application. In other words, if the power source is a battery don't use the average voltage, but the minimum voltage of the battery during normal discharge.
Here is a chart of typical values:
Vin Vout Imax Watts
3 5 2.3A 11.5W
3 12 1A 12W
3 24 0.5A 12W
5 8.4 2.4A 20W
5 12 1.7A 20W
5 19 1.1A 21W

6 12 2A 24W

24 36 2.8A 100W*
36 38 3.9A 148W*
*Wattages over 25W cannot be sustained continuously due to inadequate heat dissipation in the standard package, but can be used for short periods of time.

Application notes from customers:

My Garmin had a tendancy to reboot when the motorcycle was started. I Installed the DCBP today on my motorcycle with a 1.5 amp fuse. Works well with first try of 20V output - Garmin does not blank out in cold temps or with lots of cranking. The unit is compact and light, fits well inside headlight housing. Turns on and off with ignition switch, so no issues with battery drain. Appears to be just what i needed. Thanks. Randy B.
