AVRD operates in discontinuous mode at lighter loads and switches to continuous mode at

higher loads thus achieving a higher efficiency of at least 80% for loads of 2W and increasing

efficiency at higher loads. The variation of efficiency with load current is shown below. Also

shown is the variation of efficiency with voltage at various load currents.

Chart on the right shows the linearity in the output

voltage and current at various resistive loads.

1.1 AVRD System Features

• General purpose adjustable voltage regulator

• High Current 5A on each output (a total of 10A)

• High Efficiency of 91%

• Supply regulated DC output from unregulated DC input

• Output voltage adjustable using a 15-turn knob (each turn approximately 0.6V)

• Dual variable output voltages from a single AVRD

• SHDN signal to power OFF AVRD and the sensors at night to conserve power.

(output voltage when shutdown is 0V)

• In circuit over current latch protection

• Additional In-line fuse to protect from any over currents due to short circuit.

• Software power down from data logger

• Compatible to most sensors requiring DC excitation

• Compatible to Dynamax data loggers

• ON/OFF slide switch, LED indicator showing power ON
