Equivalent
1. Infineon IR1167 - A smart secondary-side driver IC for synchronous rectification.
2. NCP43080 by ON Semiconductor - A high-performance driver for synchronous rectification.
3. NCP4305 by ON Semiconductor - Optimized for flyback converter topologies.
4. MP6908A by Monolithic Power Systems - A secondary-side synchronous rectifier controller.
These alternatives might not be drop-in replacements and should be evaluated for compatibility.
Features
1. Dual SR Control: It manages two independent synchronous rectifiers (SRs) to enhance efficiency on both the primary and secondary sides of a flyback transformer.
2. Adaptive Dead-Time Control: Automatically adjusts the dead time between the turn-off of the primary-side switch and the turn-on of the SRs, minimizing body diode conduction and reducing power loss.
3. Wide Operating Range: Capable of operating in a wide voltage range, making it suitable for various applications.
4. Light Load Efficiency: Provides a low-power mode to maintain efficiency at light loads by reducing switching losses.
5. Protection Features: Includes features like under-voltage lockout (UVLO) and thermal shutdown for enhanced reliability and safety.
6. Compact Package: Available in a small SOIC-8 package, supporting space-constrained designs.
These features make the UCC24624DR ideal for use in high-efficiency power supply designs, where minimizing energy loss is crucial.
Pinout
1. VDD (Pin 1): Power supply input for the device.
2. GND (Pin 2): Ground reference for the controller.
3. VS (Pin 3): High-voltage sense pin to monitor the flyback transformer secondary winding voltage.
4. OUTA (Pin 4): Output driver for the gate of the synchronous rectifier MOSFET on the secondary side for one channel.
5. OUTB (Pin 5): Output driver for the gate of the synchronous rectifier MOSFET on the secondary side for the second channel.
6. CSG (Pin 6): Current sense ground pin for monitoring current through the synchronous rectifiers.
7. SW (Pin 7): Switch node sense input to detect the turn-off of the primary-side switch.
8. NC (Pin 8): Not connected; used for package mechanical stability.
The UCC24624 is designed to improve efficiency by controlling MOSFETs to replace diodes in the secondary side of flyback converters.
