UCC2305-Q1Automotive 5V to 18V HID Lamp controller | Lighting, Ballast Controllers | 3 | LTB | The UCC2305 integrates all of the functions required to control and drive one HID lamp. The UCC2305 is tailored to the demanding, fast turn-on requirements of automobile headlamps, but is also applicable to all other lighting applications where HID lamps are selected. HID lamps are ideal for any lighting applications that can benefit from very high efficiency, blue-white light color, small physical lamp size, and very long life.
The UCC2305 contains a complete current mode pulse-width modulator, a lamp power regulator, lamp temperature compensation, and total fault protection. Lamp temperature compensation is critical for automobile headlamps, because without compensation, light output varies dramatically from a cold lamp to one that is fully warmed up.
The UCC2305 is tested for full performance with ambient temperature from –40°C to 105°C.

The combination of controller and MOSFET emulates a near-ideal diode rectifier. This solution not only directly reduces power dissipation of the rectifier but also indirectly reduces primary-side losses as well, due to compounding of efficiency gains.
Using drain-to-source voltage sensing, the UCC24610 is ideal for Flyback and LLC-resonant power supplies but can also be used with other power architectures. The UCC24610 is optimized for output voltages from 4.5 V to 5.5 V, and is suitable for use with lower and higher output voltages as well.
The UCC24610 offers a programmable false-triggering filter, a programmable timer to automatically switch to light-load mode at light load, and a SYNC input for optional use in continuous conduction mode (CCM) systems. Protection features on TON and EN/TOFF pins prevent run-away on-time due to open-circuit or short-circuit fault conditions.
This device is available in an 8-pin SOIC package and an 8-pin, 3.0-mm × 3.0-mm SON package with an exposed thermal pad.

UCC24612High-frequency multi-mode synchronous rectifier controller | DC/DC & AC/DC (Off-Line) SMPS Evaluation Boards | 4 | 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.

UCC24624High-frequency, dual synchronous rectifier controller for LLC converters | Development Boards, Kits, Programmers | 3 | Active | The UCC24624 high-performance synchronous rectifier (SR) controller is dedicated forLLC resonant convertersto replace the lossy diode output rectifiers with SR MOSFETs and improve the overall system efficiency.
The UCC24624 SR controller uses drain-to-source voltage sensing method to achieve on and off control of the SR MOSFET. Proportional gate drive is implemented to extend the SR conduction time, minimize the body diode conduction time. To compensate for the offset voltage caused by the SR MOSFET parasitic inductance, the UCC24624 implements an adjustable positive turn-off threshold to accommodate different SR MOSFET packages. UCC24624 has a built-in 475-ns on-time blanking and a fixed 650-ns off-time blanking to avoid SR false turn-on and turn-off. UCC24624 also integrates a two-channel interlock function that prevents the two SRs from being on at the same time. With 230-V voltage-sensing pins and 28-V ABS maximum VDD rating, it can be directly used in converters with output voltage up to 24.75 V. The internal clamp allows the controller to support 36-V output voltage easily by adding an external current limiting resistor on VDD.
