NCP1632DR2G

Overview

The NCP1632DR2G is a two-phase interleaved power factor correction (PFC) controller designed for critical conduction mode (CrM) applications. It integrates dual MOSFET drivers with 180-degree phase shifting to reduce input current ripple and electromagnetic interference. The device operates within a supply voltage range of 10V to 20V and features a typical switching frequency of 130kHz, with a minimum operating temperature of -40°C and a maximum of +125°C. Packaged in a 16-pin SOIC, it supports surface mount installation and includes protection features such as output overvoltage/undervoltage detection and soft-start.

Feature Summary

• Integrates dual high-current MOSFET drivers capable of driving TO-220 or TO-247 packages
• Maintains precise 180-degree phase shift between phases under all transient conditions
• Supports Frequency Clamped Critical Conduction Mode (FCCrM) for optimized efficiency across load ranges
• Includes fast line/load transient compensation to minimize output voltage overshoot and undershoot

Applications

• Interleaved Power Factor Correction stages
• High-efficiency AC-DC power supplies
• Systems requiring reduced electromagnetic interference through phase interleaving

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to ensure compatibility with your design's thermal and electrical constraints before finalizing procurement.

Selection Notes

Select this controller when designing systems that benefit from interleaved topology to lower input filter size and improve thermal distribution. It is suitable for applications requiring robust drive capability for large MOSFETs without external gate driver components. Ensure the application environment stays within the specified -40°C to +125°C operating temperature range for reliable performance.

Part Context

This component belongs to the NCP1632 series of power factor controllers manufactured by onsemi. It is part of the company's portfolio focused on efficient power management solutions. The device is distinct from single-phase controllers like the NCP1606BDR2G due to its integrated dual-channel architecture specifically engineered for multi-phase interleaved operations.
