TCS5525

1.2MHz, High Efficiency Boost White LED Driver

产品描述

The TCS5525is a step-up converter designed fordriving up to 7 series white LEDs from a single cel!Lithium lon battery. The TCS5525 uses currentmode, fixed frequency architecture to regulate anLED current,which is measured through anexternal current sense resistor.
The TCS5525 includes under-voltage lockout.current limiting and thermal overload protectionpreventing damage in the event of an outputoverload.Optimized operation freguency can meet therequirement of small LC filters value and lowoperation current with high efficiency. internal softstart function can reduce the inrush current. Tinypackage type provide the best solution for PCBspace saving and total BOM cost.
