LED Drivers are widely used today, and the HLN-60H-20B is one of them. This device is a small-sized programmable constant current LED Driver that can adjust LED current according to the customer\'s demands. It is capable of stepping down the load voltage to drive multiple LED strings (up to 10 strings). The output current can be as low as 10mA and up to a maximum of 500mA.

The HLN-60H-20B provides multiple protection features that make it a highly reliable LED Driver. It has over-current protection, short-circuit protection, and overtemperature protection. Additionally, the HLN-60H-20B has a very wide input voltage range, ranging from 6V to 42V. It has variable PWM switching frequency up to 200KHz.

The HLN-60H-20B has two modes of operation: Constant Current (CC) Mode and Constant Power (CP) Mode. In Constant Current Mode, LED current is maintained at the set maximum current level without being affected by the load\'s voltage. In Constant Power Mode, the maximum power value of each LED string is maintained.

The HLN-60H-20B is a constant current LED Driver, making it an ideal choice for lighting applications. The wide input voltage range, multiple protection features, and low power consumption make it suitable for applications such as indoor/outdoor lighting, backlight applications, and automotive interior/exterior lighting.

The working principle of the HLN-60H-20B is quite simple. It uses a pulse-width modulation (PWM) and a single-ended high-side switch to control the output current. When the current is higher than the set level, the controller automatically increases the width of the pulses to reduce the current. Conversely, when the current is lower than the set level, the controller automatically decreases the width of the pulses to increase the current. This makes the HLN-60H-20B an efficient and cost-effective LED Driver.

In conclusion, the HLN-60H-20B is a reliable and efficient LED Driver with multiple features that make it suitable for a variety of lighting applications. It has a wide input voltage range, multiple protection features, and low power consumption, making it an ideal choice for both indoor and automotive use. It also has a simple working principle that makes it a cost-effective device.
