Smaller, more efficient alternative to linear regulators for driving high-brightness LEDs in step-down applications. What you proposed seems easier than using a UNL for inverted input as I was thinking at first ; So then the circuit would look at follows? However, during the term of this Agreement ON Semiconductor may from time-to-time in its sole discretion provide such Support to Licensee, and provision of same shall not create nor impose any future obligation on ON Semiconductor to provide any such Support. In this Agreement, words importing a singular number only shall include the plural and vice versa, and section numbers and headings are for convenience of reference only and shall not affect the construction or interpretation hereof. The device is compatible with switching frequencies of up to 1 MHz, making it ideal for applications requiring small footprint and low value external inductors.

CAT4201: LED Driver, 350 mA, Step-Down Converter

Request for this document already exists and is waiting for approval. Handles transients up to 40 V. Smaller, more efficient lex to linear regulators cwt4201 driving high-brightness LEDs in step-down applications. The following Sections of this Agreement shall survive the termination or expiration of this Agreement for any reason: Skorn on Mar 07, Any provision of this Agreement which is held to be invalid or unenforceable by a court in any jurisdiction shall, as to such jurisdiction, be severed from this Agreement and ineffective to the extent of such invalidity or unenforceability without invalidating the remaining portions hereof or cst4201 the validity or enforceability of such provision in any other jurisdiction.


Chagrin on Jan 18, In the CAT data sheet it is noted that a 2 Ohm resistor should be added between the 24V input and C1 to protect against too high current.

Arduino Uno, TLC and CAT how do I make them work?

Single Pin Control and Dimming function. Please allow business days for a response. I was able to hook up the TLC and the Arduino nicely. In that fat4201, “Licensee” herein refers to such company. The remedies herein are not exclusive, but rather are cumulative and in addition to all other remedies available to ON Semiconductor. BOM, Gerber, user manual, schematic, test procedures, etc. Failure by either party hereto to enforce any term of this Agreement shall not be held cat4210 waiver of such term nor prevent enforcement of such term thereafter, unless and to the extent expressly set forth in a writing signed by the party charged with such waiver.


Such license agreement may be a “break-the-seal” or “click-to-accept” license agreement. Automobiles and Aircraft General Lighting.

Parallel Configuration for Higher Output Current. Your request has been submitted for approval.

I saw that most of the people use a CAT to drive the LEDs, but this requires the use of a resistor to limit voltage and I would like to prevent that. Additional features include overload current protection and thermal shutdown.

CAT LED Driver, mA, Step-Down Converter

Previously Viewed Products Select Product The datasheet never fully answers that question and only shows current up to 35K Fig. Licensee agrees that the delivery of any Software does not constitute a sale and the Software is only licensed.

From the CAT datasheet: I added a link to the data sheet at the end. Chagrin Faraday Member Posts: Licensee agrees that it shall maintain accurate and complete records relating to its ld under Section 2. ON Semiconductor shall own any Modifications to the Software. Nothing contained in this Agreement limits a party from filing a truthful complaint, or the party’s ability to communicate directly to, or otherwise participate in either: Except as expressly permitted in this Agreement, Licensee shall not disclose, or allow access to, the Content or Modifications to any third party.
