LEDs have become the standard lighting source due to numerous advantages over traditional incandescent and arc-gas lamps. These advantages include higher efficiency, improved reliability, longer lifetimes, smaller sizes, and faster switching capabilities. For LED illumination, a constant-current regulator is essential. This is because the current of a high-power LED can double with just a 10% increase in voltage, posing a high risk of LED damage. When selecting LED illumination drivers, the topology of the power stage and flexible dimming control are two primary considerations.<\/p>

TS19605CA20H is a three-channel Linear LED driver with analog and PWM dimming control. This device targets at automotive lighting applications. It provides high-side drivers for LED current configured with the maximum current up to 150mA per channel. By cascade external PNP transistor can reach up to 400mA per channel. TS19605CA20H operates with a wide input range of 4.5V to 70V and low quiescent current in standby mode. It is designed with various protection functions such as under voltage lockout (UVLO), LED-String open load voltage protection (OLP) and short circuit protection (SCP), ISET pin open\/short protection and over-temperature protection (OTP). Diagnostic features are provided to meet automotive requirements.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
