NCP1616A2DR2G

Overview

The NCP1616A2DR2G is a high-voltage, high-efficiency boost switching controller manufactured by onsemi. It operates within a supply voltage range of 9.5 V to 28 V and supports a fixed switching frequency of 50 kHz. The device provides a single output capable of delivering up to 800 mA at 12 V. Designed for non-isolated applications, it features fast switching characteristics with rise and fall times of 40 ns and 20 ns respectively. The component functions within an ambient temperature range of -40 °C to +125 °C and is housed in a compact SOIC-9 surface-mount package.

Feature Summary

• Integrated high-voltage boost topology control for power factor correction applications
• Fixed 50 kHz switching frequency operation for simplified filter design
• Shutdown pin functionality for system power management

Applications

• Power factor correction circuits
• Boost converter designs
• High efficiency power supplies

Procurement Notes

Verify the complete part number including suffixes such as DR2G against official manufacturer documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Cross-reference the SOIC-9 package dimensions with ECAD models prior to PCB layout finalization to prevent mechanical clearance issues.

Selection Notes

Select this component when a fixed 50 kHz boost controller is required for non-isolated high-voltage applications. Ensure the input supply voltage remains within the 9.5 V to 28 V operational window. Verify that the thermal environment allows for operation up to 125 °C junction temperature. Consider the SOIC-9 package constraints for board space and thermal dissipation requirements relative to the 800 mA output capability.

Part Context

This device belongs to the NCP1616 series of switching controllers from onsemi. It is categorized under PMIC - Power Management ICs and specifically designed for boost topology applications. The component is distinct from other series like NCP1618 or NCV33161 which serve different functional roles such as multi-mode PFC or voltage supervision.
