PFC Controller 6-Pin ESIP-G Tube
Manufacturer Part #: PFS723EG
Alternate Part #: PFS723EG
The PFS723EG is incorporate a continuous conduction 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 PFS723EG is 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. PFS723EG includes standard set of comprehensive protection features, such as integrated soft-start, UV, OV, brown-in/out, and hysteretic thermal shutdown. PFS723EG also provides cycle-by-cycle current limit for the power MOSFET, power limiting of the output for overload protection, and pin-to-pin short-circuit protection.
PFS723EG 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 PFS723EG 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, PFS723EG 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 PFS723EG to realize all of the benefits of continuous-conduction mode operation while leveraging low-cost, small, simple EMI filters.
