UCC24612High-frequency multi-mode synchronous rectifier controller | Evaluation Boards | 5 | Active | UCC24612 is a high performance synchronous rectifier controller and driver for standard and logic-level N-channel MOSFET power devices. By implementing a near-ideal diode emulation UCC24612 reduces losses of the output rectifier and indirectly the primary side losses. The drain to source (VDS) sensing control scheme allows UCC24612 to work with multiple topologies, such as Active Clamp Flyback, QR/DCM/CCM Flyback and LLC, et.
Integrated features simplify the design effort, enabling UCC24612 to excel in a variety of applications and frequencies. The wide operating VDD and VD voltage ranges enable simple implementation in systems with outputs up to 28 V. Efficiency and noise immunity is enhanced with adaptive minimum off-time. Variants UCC24612-1 and UCC24612-2 offer different minimum on-times to provide additional noise immunity. Robust operation in continuous conduction mode (CCM) is further enhanced with proportional gate-drive and CCM cycle limit pre-turn-off.
UCC24612 has multiple features that improve efficiency. The fast comparator with short propagation delays reduces switching loss. The 9.5-V gate drive clamp reduces MOSFET driving losses. Frequency dependent standby modes further decreases standby power. These features help UCC24612 be part of a greater system that meets stringent efficiency standards such as Department of Energy (DoE) Level VI and Code of Conduct (CoC) Tier 2.
UCC24612 is available in a SOT23-5 package.

UCC24650200-V wake-up monitor for fast transient primary-side regulation | Power Management (PMIC) | 2 | Active | The UCC24650 is an easy-to-use secondary-side voltage monitor that periodically measures its own VDD voltage. A relative droop of 3% from the previous reading triggers a alert signal to a receiving primary-side regulation (PSR) controller. Its low-power consumption helps achieve <5-mW standby loss in many applications.
An internal 200-V MOSFET switch is applied across a ground-referenced rectifier to provide a current-limited pulse to the flyback transformer secondary winding, which couples the signal to the primary-side controller. This signal is repeated at 33 kHz until controller-driven switching activity is detected.
Relative-droop detection allows scaling to any voltage between 5 and 28 V. The alert function allows very-low standby frequency to minimize switching loss and reduction of output capacitance needed to respond to a heavy load step. This monitor is used with a controller capable of detecting the signal, such as the UCC28730 PSR flyback controller.
The UCC24650 also provides an enable and disable signal which can be used to control a secondary-side circuit during no-load conditions to reduce standby power loss. Such a circuit may be a synchronous rectifier controller or a relay driver, for example.
