STLDC08 Datasheet | STMicroelectronics

Step-up controller for LED supply Features - Input voltage range from 0.8 V to 3.6 V - Overvoltage protection - Drives N-channel MOSFET or NPN bipolar transistor - No control loop pensation required - FET driver for very precise PWM dimming Applications - Single/dual cell NiMH, NiCd, or alkaline batteries - Small appliances LED lighting - Portable lighting Description The STLDC08 LED driver step-up controller is optimized to operate from one or two NiCd/NiMH or alkaline cells. The IC is able to drive an external MOSFET (N-channel) enabling it for use with wide power levels. Hysteretic control eliminates the need for small signal control loop pensation. The IC integrates an...
