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.

This reference design implements the UCC28630 PSR controller in a flyback power supply. The UCC28630 is capable of operating in both Continuous and Discontinuous Conduction Modes which enables high efficiency while reducing inductor size and cost. Safety standards such as EN60950 require that any X-capacitors in EMC filters on the AC side of the bridge rectifier quickly discharge to a safe level when AC is disconnected. Typically, this requirement is achieved by including a resistive discharge element in parallel with the X-capacitor. However, this resistance causes a continuous power dissipation that impacts the standby power performance. In order to reduce standby power and eliminate the standing loss associated with the conventional discharge resistors, the UCC28630 device incorporates active X-capacitor discharge circuitry. In this design, less than 100mW no load power comsumption and over 88% converter efficiency is achieved.
