Overview
The ACT43950-T is a high-voltage constant current capacitor charging controller manufactured by Qorvo. Designed for integration with silicon carbide (SiC) power switches, this component provides fully programmable output voltage and current capabilities. It serves as the primary stage in advanced power solutions for phased array radar systems, working in conjunction with subsequent regulation stages to minimize energy storage capacitor requirements while maximizing system performance.
Feature Summary
- Provides fully programmable output voltage and current settings
- Functions as a high-voltage constant current capacitor charging controller
- Integrates with SiC power switches to optimize system architecture
Applications
- Phased array radar systems
- High-voltage capacitor charging circuits
- RF GaN power amplifier biasing networks
Procurement Notes
Verify the specific suffix against official Qorvo documentation to confirm tape-and-reel specifications and temperature grades. Ensure compatibility with associated SiC switches and downstream regulators like the ACT43850. Confirm end-of-life status and lead times through authorized distributors prior to design finalization.
Selection Notes
Select this component when designing high-voltage charging stages for radar arrays requiring precise current control. It pairs effectively with the ACT43850 RF load point converter and ACT43750 gate driver PMIC. Evaluate thermal management needs for high-voltage operation and ensure PCB layout supports the required switching frequencies and noise immunity.
Part Context
This part belongs to Qorvo's advanced power management portfolio for professional applications. It complements the ACT43850 and ACT43750 to form a complete three-chip solution for RF GaN power amplifiers. The series targets high-performance radar systems where minimizing passive component size and optimizing bias stability are critical design constraints.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Designers should consult Qorvo directly for legacy replacements or pin-compatible alternatives if discontinuation occurs.
