The 11020CL0 is a specially designed DC/DC converter that is used to charge a battery from a
12V source. An example is a battery that is mounted on the trailer of a vehicle. The distance

between the alternator of the vehicle and the trailer-mounted battery makes it difficult to get

adequate charging voltage to the battery. The 11020CL0 has a microprocessor on-board to

measure the input voltage, output voltage and current, boost voltage, temperature sensors, as

well as monitoring the shutdown and reduce commands input to the unit. The lockout feature is

provided via an Intelligent Power Switch on the output, to provide consistent, robust protection

and control of the output current.

The 11020CL0 has four modes of operation:

• Boost Mode: This mode is enabled when input voltage is nominal (e.g.. Vin ≤ (Vout + 0.6 Vdc)). When the converter is operating in this mode, the output voltage is temperature compensated, see graph 1.

• Bypass Mode: This mode is enabled when the input voltage is greater than the outputvoltage. In this mode, the converter will enter a “burst” operation whereby the output will burst on and off when the pass through current exceeds 20ADC. If the Reduce command is active, then the unit will burst if the pass through current exceeds 10ADC.

• Reduced Power Mode: This mode is enabled when the REDUCE or REDUCE pin, isactive (e.g. REDUCE

≥ 3Vdc or REDUCE ≤ 3Vdc). In this mode the output is current limited to approximately 12A. Reduced power mode is effective during nominal Boost Mode operation and while in Bypass mode. In bypass, bursting will allow up to ~11A RMS in reduce mode and up to ~22A RMS without the reduce command.

• Shutdown Mode: This mode is enabled when the SD pin is active (e.g. SD ≥ 3V). In this mode the charger output is shutdown and will not charge
