QPO-1 SiP SPECIFICATIONS (-20°C to +100°C PCB Substrate temperature)
Electrical Characteristics
Electrical characteristics apply over the full operating range of input voltage, output power and PCB substrate temperature, unless
otherwise specified. All temperatures refer to the operating temperature at the interface of the PCB surface with proper reflow mounting of
QPO-1. The PCB surface must have sufficient area and heat via’s to the opposite side to achieve the optimum thermal resistance.

There is no internal current limiting. The system must
be properly fused such that the current does not exceed
the absolute maximum rating of 15A. A minimum
current of 30mA is needed to maintain regulation.

(without slope adjust or peak detection.)
(1) Headroom voltage, peak detection and slope adjustment must be chosen by the user based on attenuation and efficiency requirements.
The functional description section explains how to optimize the configuration of the QPO-1 for the voltage source used. The headroom
voltage is the difference between the input and the output of the QPO-1 and is set by the selection of resistor RHR.
Calculate RHR as shown.
RHR = (QPOOUT / VHR) x 2.5k (see Table 1 for example values)
(2) RSS resistor sets the correction current required to trim the source output up to accommodate the headroom of the QPO-1 when remote
sense is not used. This function will accommodate power supplies with positive reference based trim configuration.
RSS = RIN * VOUT / VRPT ( If a converter is trimmed down use the resulting VOUT voltage in the formula for RSS)
Where:
RIN = input resistance of the SC or Trim pin;
VOUT = source output voltage;
VRPT = SC or Trim pin pre-trimmed reference
