Infineon LITIX Power TLD5190-1QV Скачать руководство пользователя страница 4

Страница: 4 / 12

Quick Start

›

Connect battery to VS and GND (8V – 40V)

›

Connect LED load (e.g. 10 white LEDs) to OUT+ and OUT-

–

LED forward voltage has to be within short circuit and output

overvoltage protection values.

›

Select compensation network (default 10nF J1 position 3-4 closed)

›

Close JP2

›

Connect TPEN (low active) and TPPWMI to digital supply (e.g. 5V)

›

Switch ON supply
