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 R
HR
.
Calculate R
