The PMP10596 reference design is an LED driver based on SIMPLE SWITCHER® LM46002 buck regulator. The driver board takes 24V +/-25% input voltage and supplies700mA output current to drive up to 4 LEDs in series. The LM46002 is a 60V, 2A synchronous buck regulator with integrated FETs, and in this design it is configured as a high efficiency constant current converter. This is accomplished by using the voltage across a current sense resistor as the feedback signal. To reduce the sense resistor power loss, a 2V voltage reference is used to bias the FB pin via a resistor network, and, as a result, the equivalent feedback reference voltage becomes 0.35V, lower than the 1V feedback of the LM46002. The reference board employs 3 dimming schemes, which allows the output current to be adjusted via the potentiometer, an analog voltage or a PWM signal. It also offers easy and flexible control to dim the LED brightness andadds output overvoltage protection from LED open-circuit failure.

Возможности:

• 24V +/-25% input voltage range, drive up to 4 LEDs • 94% efficiency driving 4 LEDs • Simple voltage bias circuit to reduce sense resistor lost • 3 flexible dimming options • LED open circuit protection • This circuit board is tested, and the design files and test report are included.

The TIDA-01494 reference design is a compact, high efficiency, 24-V DC, 480-W nominal, 720-W peak output reference design for industrial AC/DC power supplies. The circuit consists of a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit followed by a robust LLC stage with synchronous rectification. The design enables efficiency greater than 93.5% over a wide load range, allowing the system to work without forced cooling. The LLC stage, based on the UCC256301, takes advantage of the ZCS avoidance feature in the UC256301 to enable peak output power, minimizing the PFC Bulk capacitor for meeting holdup requirements, while making the system robust to short circuit and over current conditions. The UCC24612-2 based synchronous rectifier helps in minimizing the losses in the output rectifier, while its advanced proportional gate drive and dead time optimization features helps to avoid shoot through and minimizes losses.
