Remote ON/OFF. Positive logic

ON:

Pin 3 open; or V > Vin - 0.5 V

OFF:

Pin 3 GND; or V < 0.6 V

See Figure 1 for safe operating curve.

A 680 µF electrolytic input capacitor is required for proper operation as

well as a 2 2µF high-frequency ceramic capacitor. The electrolytic

capacitor must be rated for a minimum of 750 mA rms of ripple current.

4

An external output capacitor is not required for basic operation. Adding

33 0µF of distributed capacitance at the load will improve the transient

response.

If utilized Vout will track applied voltage by ±0.3 V (up to Vo set point).

7

The pre-bias start-up feature is not compatible with Auto-Track™. This is

because when the module is under Auto-Track™ control, it is fully active

and will sink current if the output voltage is below that of a back-feeding

source. Therefore to ensure a pre-bias hold-off, one of the following two

techniques must be followed when input power is first applied to the

module. The Auto-Track™ function must either be disabled, or the

module’s output held off using the Inhibit pin. Refer to Application Note

197 for more details.

8

The set-point voltage tolerance is affected by the tolerance and stability

of Rset. The stated limit is unconditionally met if Rset has a tolerance of

1% with 100/

ºC or better temperature stability.

To order Pb-free (RoHS compatible) through-hole parts replace the

mounting option ‘H’ with ‘D’, e.g. PTV03020WAD.

The ultra-wide output voltage trim range offers major advantages to users who

select the PTV03020. It is no longer necessary to purchase a variety of

modules in order to cover different output voltages. The output voltage can be

trimmed in a range of 0.8 Vdc to 2.5 Vdc. When the PTV03020 converter

leaves the factory the output has been adjusted to the default voltage of 0.8 V
