Thông Tin Sản Phẩm
Tổng Quan Sản Phẩm
The MAX16814BEUP+ is a integrated, 4-channel, high brightness LED driver with high voltage DC-DC controller in 20 pin TSSOP package. It consists of 4 identical linear current source channels to drive 4 strings of HB LEDs. The channel current is adjustable from 20mA to 150mA with an accuracy of ±3% using an external resistor. External resistor sets all 4-channel currents to same value. Device allows connecting multiple channels in parallel to achieve higher current per LED string. It features pulsed dimming control on all four channels through a logic input (DIM), a unique feature that allows a very short minimum pulse width as low as 1µs. It includes output overvoltage, openLED detection and protection, programmable shorted LED detection and protection and overtemperature protection. It is used in automotive displays LED backlights, automotive RCL, DRL, front position and fog lights, LCD TV and desktop display LED backlights, architectural, industrial and ambient lighting.
- Operating voltage range from 4.75V to 40V
- Operating temperature range from -40°C to 85°C
- 5000:1 PWM dimming at 200Hz, less than 40µA shutdown current & 200KHz to 2MHz programmable switching
- Minimal component count saves cost and space
- Internal MOSFET for each channel
- DC-DC controller supporting boost, coupled-inductor boost-buck or SEPIC topologies
- Frequency for optimizing size versus efficiency
- External switching frequency synchronization
- Open drain fault indicator output, overtemperature protection
- Open LED and LED short detection and protection
