Digitally (or analog) controlled constant current source

Custom design and manufacture of state-of-the-art battery chargers, UPS, and power supplies for OEMs in a hurry?

Digital or analog controlled constant current source

This is a microprocessor controlled SEPIC topology DC/DC converter programmed to be a constant current power source.

Theory of Operation:

A serial digital signal or analog voltage sets the current in this constant-current power supply board.

Output voltage can be higher or lower than the input voltage.

Form factor and custom features can be redesigned to OEM requirements.

PST-SEP-CC Preliminary specifications
Input voltage	8-30 volts nominal, higher range possible
Compliance Voltage:	1.8-18 volts nominal
Output Current	0-2 amps
Control method	Serial digital signal or analog 0-5 volts
Bandwidth	1 kHz
Efficiency	50% (low power) to 80% (27 watts output)
Form	Circuit board product, (frame or case developed on request)
Dimensions	4" x 1.8" x 0.5" (10 cm x 4.6 cm x 2 cm)
Weight	1.2 oz, 34 grams

Note: Compliance voltage is the range of output voltage available to control a fixed current. For example, if a constant current of 0.5amps is desired then the load resistance can range between 3.6 Ohms and 36 Ohms
