NOTES

(1)

ESR

≥1mΩ / ESR≥10mΩ, Test by minimum input and constant resistive load.

(2)

Vin(nom), 3.3VDC @ Full Load

(3)

It’s necessary to equip the external input capacitors at the input of the module. The capacitors should connect as close as possible to the input

terminals ensuring module stability. The external Cin is 3pcs of 150µF low-ESR polymer capacitors // 2pcs of 47µF ceramic capacitors at least.

(4)

Output voltage is programmable from 0.75V to 3.3V by connecting a single resistor (shown as Trim Table) between the Trim and GND pins of the

module. To calculate the value of the resistor Rtrim for a particular output voltage Vout, use the following equation:

(5)

Remote On/Off referred to –Vin pin

(6)

Positive Logic: ON/OFF is open collector/drain logic input

Negative Logic: ON/OFF pin is open collector/drain logic input with external pull –up resistor.

(7)

Case 1: ON/OFF input is set to logic low (module on) and then input power is applied (delay from instant at which Vin=Vin(min.) until Vout=10% of

Vout(set))

Case 2: Input power is applied for at least one second and then the ON/OFF input is set to logic low (delay from instant at which Von/off=0.3VDC

until Vout-10% of Vout(set))

CAUTION: This power module is not internally fused. An input line fuse must always be used.

*Due to advances in technology, specifications subject to change without notice.
