Output Voltage Adjustment of the PTV05020 Series
The ultra-wide output voltage trim range offers major advantages to users who
select the PTV05020. 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 3.6 Vdc. When the PTV05020 converter
leaves the factory the output has been adjusted to the default voltage of 0.8 V
1 Remote ON/OFF. Positive logic
ON: Pin 3 open; or V > Vin - 0.5 V
Pin 3 GND; or V < 0.6 V
2 See Figure 1 for safe operating curve.
3 A 680 µF electrolytic input capacitor is required for proper operation as
well as a 22 µF 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
330 µF of distributed capacitance at the load will improve the transient
5 1 A/µs load step, 50 to 100% Iomax, C3 = 330 µF.
6 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
198 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.
9 To order Pb-free (RoHS compatible) through-hole parts replace the
mounting option ‘H’ with ‘D’, e.g. PTV05020WAD.
