NCP1603D100R2

Overview

The NCP1603D100R2 is a Power Factor Correction and Pulse Width Modulation Combo Controller manufactured by onsemi. It integrates high-voltage startup and standby capabilities within a single package. The device operates in voltage-mode control with pulse width modulation techniques. It supports peak current mode operation as an alternative control scheme. The component is housed in a 16-pin SOIC (SOP-16) package. Electrical specifications include a maximum input voltage of 18 V and a minimum input voltage of 9 V, with a nominal input voltage of 13 V.

Feature Summary

• Integrates PFC and PWM functions into a single controller unit
• Features built-in high-voltage startup circuitry for simplified design
• Includes dedicated standby capability for low-power applications
• Supports both voltage-mode and peak current mode control strategies

Applications

• Power factor correction circuits with post-regulator requirements
• High-efficiency AC-DC power supply designs
• Systems requiring integrated startup and standby management

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and compliance status. Confirm RoHS and Reach compliance details directly from the manufacturer's datasheet or official documentation before procurement. Check for any specific environmental certifications required for your target market. Ensure the package type matches your PCB footprint requirements. Validate that the component meets all relevant regulatory standards for your application.

Selection Notes

Select this component when a combined PFC and PWM solution is required to reduce bill of materials count. Consider its integrated high-voltage startup feature if external bias supplies are undesirable. Evaluate its standby capability against system power consumption targets. Verify compatibility with voltage-mode or peak current mode control loops. Ensure the 16-pin SOIC package fits the available board space constraints.
