Description
The HiperPFS device family members incorporate a continuous
condition mode (CCM) boost PFC controller, gate driver, and
high voltage power MOSFET in a single, low-profile eSIP
power package that is able to provide near unity input power
factor. The HiperPFS devices eliminate the PFC converter’s
need for external current sense resistors, the power loss
associated with those components, and leverages an innovative
control technique that adjusts the switching frequency over
output load, input line voltage, and even input line cycle. This
control technique is designed to maximize efficiency over the
entire load range of the converter, particularly at light loads.
Additionally, this control technique significantly minimizes the
EMI filtering requirements due to its wide-bandwidth spread
spectrum effect. HiperPFS includes Power Integrations’
standard set of comprehensive protection features, such as
integrated soft-start, UV, OV, brown-in/out, and hysteretic
thermal shutdown. HiperPFS also provides cycle-by-cycle
current limit for the power MOSFET, power limiting of the output
for over-load protection, and pin-to-pin short-circuit protection.
HiperPFS’s innovative variable-frequency continuous conduction
mode of operation (VF-CCM) minimizes switching losses by
maintaining a low average switching frequency, while also
varying the switching frequency in order to suppress EMI, the
traditional challenge with continuous-conduction-mode
solutions. Systems using HiperPFS typically reduce the total X
and Y capacitance requirements of the converter, the inductance
of both the boost choke and EMI noise suppression chokes,
reducing overall system size and cost. Additionally, compared
with designs that use discrete MOSFETs and controllers,
HiperPFS devices dramatically reduce component count and
board footprint while simplifying system design and enhancing
reliability. The innovative variable-frequency, continuous
conduction mode controller enables the HiperPFS to realize all
of the benefits of continuous-conduction mode operation while
leveraging low-cost, small, simple EMI filters.
Many regions mandate high power factor for many electronic
products with high power requirements. These rules are
combined with numerous application-specific standards that
require high power supply efficiency across the entire load
range, from full load to as low as 10% load. High efficiency at
light load is a challenge for traditional PFC approaches in which
fixed MOSFET switching frequencies cause fixed switching
losses on each cycle, even at light loads. HiperPFS simplifies
compliance with new and emerging energy-efficiency standards
over a broad market space in applications such as PCs, LCD
TVs, notebooks, appliances, pumps, motors, fans, printers, and
LED lighting.
HiperPFS advanced power packaging technology and high
efficiency simplifies the complexity of mounting the package
and thermal management, while providing very high power
capabilities in a single compact package; these devices are
suitable for PFC applications from 75 W to 1 kW
