The ILD6150XUMA1 is a LED driver IC for high power LEDs in PG-DSO-8-27 package. This is a hysteretic buck LED driver IC for driving high power LEDs in general lighting applications with average currents up to 1.5A. A multifunctional PWM input signal allows dimming of LEDs with an analogue DC voltage or an external PWM signal. To minimize colour shifts of LEDs an analogue PWM voltage is converted to an internal 1.6KHz PWM signal modulating LED current. It incorporates an undervoltage lock-out that shut down IC when minimum supply voltage threshold is exceeded. An integrated over temperature protection circuit will start to reduce LED current by internal PWM modulation once adjustable junction temperature threshold of IC is exceeded. Realizing thermal coupling between LED driver IC and LEDs will eliminates need of external temperature sensors as NTCs or PTCs. It is used in LED driver for general lighting, retail, office, residential downlights, street & tunnel lighting and LED ballasts.
- Wide input voltage range from 4.5V to 60V
- Up to 1MHz switching frequency, capable to provide up to 1.5A average output current
- Soft-start capability
- Analogue and PWM dimming possible
- Integrated PWM generator for analogue dimming input
- Typical 3% output current accuracy
- Very low LED current drift over temperature
- Adjustable over temperature protection
- Undervoltage lockout, over current protection
- Over-current protection turns off output stage once output current is above current threshold
