RT8470: 1A, Hysteretic, High Brightness LED Driver with Internal Switch

(PresseBox) (Quickborn, ) Texim Europe recently introduced the RT8470 from Richtek, a highefficiency, continuous mode inductive stepdown converter, designed for driving single or multiple series connected LEDs from a voltage source higher than the LED voltage. It operates from an input voltage of 7V to 30V and employs hysteretic control with a highside current sense resistor to set the constant output current.

The RT8470 includes the output switch and a highside output current sensing circuit, which uses an external resistor to set the nominal average output current. LED brightness control is achieved with PWM dimming from an analog or PWM input signal.


Input voltage range: 7 to 30V
Hysteretic control with highside current sensing
Internal N-MOSFETs
Output current: 1A
Up to 95% efficiency
Typical ±5% LED current accuracy
Analog or PWM control signal for PWM dimming
300Hz onboard ramp generator
Input under voltage lockout
Thermal shutdown protection
