MT7605 Segmented, Linear Constant - Current LED Driver DESCRIPTION MT7605 is a segmented linear constant - current LED driver. It operates in linear mode

The PT4115 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage. The device operates from an input supply between 6V and 30V and provides an externally adjustable output current of up to 1.2A. Depending upon the supply voltage and external components, the PT4115can provide more than 30 watts of output power.The PT4115 includes the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current, and a dedicated DIM input accepts either a DC voltage or a wide range of pulsed dimming. Applying a voltage of 0.3V or lower to the DIM pin turns the output off and switches the device into a low current standby state.The PT4115 is available in SOT89-5 and ESOP8 packages

SMD LEDs stand for Surface Mount Device and Light Emitting Diode. The combination of these acronyms indicates electronic components made up of LED modules that are mounted directly on one side of the printed circuit board using surface mount technology, known as SMT

An IC can function as an amplifier, oscillator, timer, counter, logic gate, computer memory, microcontroller or microprocessor. An IC is the fundamental building block of all modern electronic devices.

The BP5151dh is a high precision primary-side regulation PWM controller with single stage Active PFC, specially designed for universal input offline flyback or buck-boost constant current LED lighting. The controller with on-chip PFC circuit achieves high power factor and low THD. Operating in critical conduction mode, the power MOSFET switchingloss is reduced and the inductoris fully utilized. Badopts proprietary primary side current sensing scheme. It can precisely control the LED current without secondary side sense and feedback circuits. The system size and cost areoptimized, as well as the system reliability. The Butilizes patented line and load voltage compensation method to achieve excellent line and load regulation.And the line compensation factor can also be tuned externally for flexibility. The BP5151DHBoffers rich protectionfunctions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC over voltage protection, VCC under voltage protection, CS resistor open protection and cycle by cycle current limit. All the protection functions are auto-recovery. The systemreliability is further improved by the thermal regulation function. The output current is reduced when the controller is over temperature.
