CPC has over 50 yrs experience as a leading distributor of electronic components for business & home. Connecting a constant logic low will disable the output, and the LM3404/04HV is enabled if the DIM pin is open-circuited. Components-Mall is a high-service distributor of technology products, services and solutions for electronic system design, maintenance and repair.
Micrel, Inc.MIC4682June 20076M9999-061507Typical Characteristics (continued)210215220225 datasheet search, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes and other semiconductors. The PWM signal is taken from the output of the U2352 to the DIM input of the LM3404 and imposes a 10 kHz pulse-width modulation on the light produced. The LM3404 RGB LED Driver was selected since each channel is sinking current from two LED RGBs and has the potential to sink more current than recommended in the data sheet. Ideal for automotive, industrial, and general lighting applications, they contain a high-side N-channel MOSFET switch with a current limit of 1.5A (typical) for step-down (Buck) regulators. Datasheet min/ max specification limits are guaranteed by design, test, or statistical analysis.
The is an ultra high speed monolithic op amp, with a typical -3dB bandwidth at a gain of +2. Normally this “quasi-hysteretic” control senses the input voltage and adjusts the on-time tON of the power MOSFET as needed to keep fSW constant. Transtector TVSS AC power protection device PDF datasheet with details of specifications and CAD drawing with dimensions for 1000-682-4 can be found above. It is not clear from the datasheet whether resistor R4 is strictly necessary for internal voltage stabilization.
In this article, we will go over how to build a voltage comparator circuit using an LM393. Design Example 1: LM3404 The first example circuit will guide the user through component selection for an architectural accent lighting application. Data sheet minimum and maximum specification limits are specified by design, test, or statistical analysis. New commercial power electronic controllers come to the market almost everyday to help improve electronic circuit and system performance and efficiency.

The constant on-time (COT) control method used by the LM3402 and LM3404 constant-current buck regulators provides a balance between control over switching frequency and fast transient response. Mouser offers inventory, pricing, & datasheets for Texas Instruments LM340T5 Linear Voltage Regulators. DEVICE MARKING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 10 of this data sheet.

Smart Filtering As you select one or more parametric filters below, Smart Filtering will instantly disable any unselected values that would cause no results to be found. With an array of LEDs, the main challenge is to ensure every LED in the array is driven with the same current. With a low cost business model we can offer you the 'Best Price' the first time, engineering support, technical datasheets, and more.
The present application is generally directed to systems and methods for control and management of lighting components connected in a network. Ideal for automotive, industrial, and general lighting applications, these devices contain a high-side N-channel MOSFET switch with a current limit of 1.5-A (typical) for step-down (Buck) regulators.
This demonstration circuit is designed to drive a single Seoul Semiconductor Z–Power P4 LED at a forward current of 1A 10% with a peak–to–peak ripple current of 200 mA or less. The LM3404 is a "Constant Current Buck Regulator for Driving High Power LEDs." One of the features the datasheet boasts is "LED dimming using pulse width modulation (PWM)." My question is, using this chip (and its associated support ciruitry), which of the following accurately reflects the nature of the current delivered to the LEDs? Texas Instruments LM340T5 Linear Voltage Regulators are available at Mouser Electronics. A small solution size is also important, as the regulator must fit on a circular PCB with a 1.5" diameter. Datasheet min/max specification limits are specified by design, test, or statistical analysis. LM1085 3A Low Dropout Positive Regulators General Description The LM1085 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 3A of load current. Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. LED matrix drivers are monolithic high-efficiency LED drivers designed to supply LED arrays used in the backlighting of LCD panels in consumer, industrial and automotive applications.
Newark offers fast quotes, same day shipping, fast delivery, wide inventory, datasheets & technical support. The logic of DIM1 is direct, hence the LM3404/04HV will de- liver regulated output current when the voltage at DIM1 is high, and the current output is disabled when the voltage at DIM1 is low. Instead of the photo resistor, the solar cell is directly connected to the IC for daylight level detection, and an optional resistor sets the light threshold.
