The AL5802 combines a high gain NPN transistor with a pre-biased NPN transistor to make a simple small footprint LED driver. The LED current is set by an external resistor connected from REXT pin (6) to GND pin (4). The internal high gain transistor develops approximately 0.6V across the external resistor.

Demonstration Circuit 1827A features a 110V LED controller with spread spectrum frequency modulation – the LT®3795. Unlike most boosts, the circuit disconnects the output to protect against shorts or other fault conditions when the input voltage exceeds the output. The input voltage range for normal operation is from 8V to 60V. OVLO becomes active for inputs above 63V and the maximum input voltag…

Demonstration circuit 2020A is a 60VIN, 80VOUT LED driver. It generates its own PWMOUT waveform from its internal PWM generator for accurate PWM dimming with up to 33:1 brightness ratio. It accepts an input voltage from 5V to 60V and drives up to 67V of LEDs at 300mA (when PVIN is less than VLED). DC2020A features both PWM and analog dimming of the LED string. It has an OPENLED flag that indicate…
