 · Exar AC Step Driver for LED Bulbs Improves Line Regulation by 2x XR targets A19 LED bulbs with more integrated two-step current controller. Sept Rev D SP 29V High Voltage LED Driver © Exar Corporation Page 4 GENERAL OVERVIEW The SP is a fixed frequency, Voltage-mode, non-synchronous buck PWM controller optimized for driving LEDs. Constant LED.  · LED driver protection modes The XRP from Exar is a A V step-down, high-brightness, LED driver using a “floating buck” topology. Besides having an input voltage range meeting the needs of the relatively new EMerge Alliance, it includes several features to ensure safe operation under abnormal operating conditions.

align="justify"Exar Corporation (Nasdaq: EXAR) released a new LED driver with inductive boost capabilities giving system architects additional design options for backlighting applications. The SP is ideal for small display/keypad LED lighting applications found in handheld portable devices such as PDAs, cell phones and data collection devices. Description. The XR is a two-step LED current controller for AC step driving with improved line regulation primarily for A19 LED bulb applications. It integrates two steps of current control to the LED strings and greatly improves the line regulation of the circuit by monitoring the line voltage and adjusting LED drive current proportionally. The XR can drive an external N-channel power MOSFET to regulate the current flowing through a high voltage (HV) LED string.
