AP1661P-E1 - 14.5V 0.8A BCM PFC Controller | Diodes Inc.
The Diodes Incorporated AP1661P-E1 is a boundary-conduction-mode power-factor-correction controller rated for 14.5 V supply operation, 0.8 A output, and a -40°C to +85°C temperature range, supplied in an 8-DIP package. It is designed primarily as a boost pre-converter controller for power-supply systems that require active input-current shaping and improved power factor. A power-factor-correction controller is a specialized power-management IC used in the hierarchy power supply control → PFC controller → AC/DC power conversion. In a boost PFC stage, it commands a switching power stage so that input current is drawn with a shape closer to the AC input voltage. That action reduces reactive current and helps the upstream system meet harmonic and power-factor targets while charging a downstream DC bus. Verified source material identifies boundary-conduction mode, 14.5 V supply operation, 0.8 A output, -40°C to +85°C operation, an 8-DIP package, and RoHS compliance. The controller is intended for compact power-supply designs where active PFC is required, including offline AC/DC converters and boost pre-regulators. Its through-hole package supports conventional PCB assembly rather than a surface-mount land pattern. The AP1661 family is associated with a BCM operating approach, allowing the power stage to conduct for a controlled interval during each switching cycle. This can reduce switching losses compared with continuous-conduction operation over part of the operating range, although actual efficiency depends on the switch, inductor, rectifier, input voltage, output voltage, and load. The controller does not provide the complete boost converter; external power-stage components are required. A key design consideration is validating the complete PFC loop with the intended magnetics and switching components. Keep the high-current boost path compact and separate from sensitive control traces, provide suitable input and output capacitors, and verify startup, current-sense limits, gate-drive behavior, and thermal margin over the required line and load ranges. The controller’s -40°C to +85°C specification should be checked against the enclosure’s worst-case ambient temperature. This product page combines verified AP1661P-E1 specifications, sourcing information, cross-reference results, and practical engineering guidance. It distinguishes verified values from unavailable manufacturer details and does not infer pricing, pin assignments, or electrical limits that were not supplied in the source data.
