CL7 Datasheet | Supertex

Features - - 100m A ±5% constant current drive - - Built-in reverse polarity protection - - Logic level enable - - Dimmable via EN pin - - Overtemperature protection - - 90V max rating for transient immunity Applications - - Flashlights - - Specialty lighting - - Low voltage signage - - Low voltage lighting General Description The CL7 is a linear fixed current regulator designed for driving high brightness LEDs at 100m A from nominal 12V, 24V, and 48V power supplies. With a maximum rating of 90V, it is able to withstand transients without the need for additional transient protection circuitry. The CL7 is offered in the 8-Lead SOIC package. An active low enable input (EN) allows logic level control of the LED for on/off control or PWM dimming. The enable input has 100kΩ pull-down resistance. For applications not needing an enable input, refer to the CL6 data sheet. Over temperature protection shuts off the LED current when the die temperature rises above 135°C (nominal). Full LED current resumes when the die temperature falls below 105°C (nominal). Typical Application Circuit Host Controller 100m A VDD Control 100kΩ Doc.# DSFP-CL7 A030314 Supertex inc. .supertex.
