|Title||LED Lighting Development Tools 0.55 A, positive buck-boost LED driver board based on LED6000|
STMicroelectronics LED6000 Step-Down Monolithic Switching Regulators are designed to source up to 3A DC current for high power LED driving. The 250mV typical RSENSE voltage drop enhances the efficiency. Digital dimming is implemented by driving the dedicated DIM pin. The adjustable current limitation, designed to select the inductor RMS in accordance with the nominal output LED current, and the adjustability of the switching frequency allow the size of the application to be compact. The embedded switchover feature on the VBIAS pin maximizes efficiency. Multiple devices can be synchronized by sharing the SYNCH pin to prevent beating noise in low-noise applications, and to reduce the input current RMS value. The device is fully protected against overheating, overcurrent and output short-circuit. The LED6000 is available in an HTSSOP16 exposed pad package.

The STEVAL-ILL088V1 evaluation board is based on a monolithic current source for high power LED driving, the 61 V asynchronous switching regulator. With embedded power MOSFET, it is designed to source A DC current depending on the application conditions. The 250 mV typical RSENSE voltage drop, the VBIAS pin embedded switch-over feature and the light load management (pulse skipping) maximize power conversion efficiency across the entire load range. Digital dimming is implemented by driving the dedicated DIM pin. The current limit threshold and the switching frequency are adjustable for application optimization. The device also includes a 250 kHz oscillator that can be externally adjusted to 1.5 MHz. The size of the overall application is minimized thanks to the high switching frequency and its compatibility with ceramic output capacitors. Two LED6000 regulators can be synchronized a 180° out-of-phase configuration to reduce the total input RMS current.Features
