EVM User's guide:
Data sheet:
The UCC25661x family is a high-frequency LLC controller implementing input-power proportional control (IPPC) scheme, along with an enhanced light-load management and multiple protection features.
IPPC widens the control range of the LLC converter simplifies the design of wide input and output-voltage range applications such as LED drivers, battery chargers. It can even work without a PFC for non-universal input applications.
The UCC25661x family has enhanced light-load management that improves the efficiency while minimizing audible noise. To minimize standby power, the UCC25661x family can directly disable the PFC controller when operating in burst mode.
The automatic capacitive region avoidance scheme along with the adaptive soft start with reverse recovery avoidance scheme ensures that the device can never work in a mode where there is a potential to damage the FETs. This scheme makes the controller ideal for working with a pre-biased load.
The UCC25661x family comes with robust protection to help you design a reliable power supply. The UCC25661x family has options supporting high-voltage startup, X-capacitor (X-cap) discharge, OVP response, and extended Gain range. See details in the Device Comparison Table.
- 50kHz to 750kHz full-load switching frequency
- IPPC control enables wide input and output LLC (WLLC) operation
- Enhanced light load management:
- High frequency pulse skip for improved light load efficiency
- Low frequency burst for low standby power
- Audible frequency range skip for reduced audible noise
- Integrated PFC on/off control signal to help further reduce standby power
- Internal resonant-capacitor voltage synthesizer for enhanced signal reliability and high startup frequency support
- Automatic capacitive region avoidance
- Adaptive soft start with minimized inrush current
- Integrated high-voltage startup (UCC256610, UCC256611, UCC256612, and UCC256614)
- X-capacitor discharge (UCC256610, UCC256611 and UCC256614).
- Integrated +0.6/-1.2A gate drive
- Complete protections
- 50ns Over-Current Protection (OCP) - cycle-by-cycle current limit
- Over-Voltage Protection (OVP), internal and external Over-Temperature Protection (OTP)
- Input and VCCP UVLO with internal 19V VCCP Clamp
- SOIC-14 package with removed pins for high-voltage clearance
