BH6048KN-E2

A PMIC (power management integrated circuit) is a device designed to provide an efficient and effective current or voltage supply to multiple loads. LED drivers are PMICs designed to drive and control LED (Light Emitting Diode) arrays. Examples of LED drivers include the BH6048KN-E2, a buck regulator type LED driver.

Application Field

The BH6048KN-E2 is used for applications that require a constant current/voltage source for LED lighting. Applications include LED tube lights, LED backlights, LED modules, and LED lamps that are used in architectural, automotive and industrial lights. In addition, the BH6048KN-E2 can be used as an LED dimming controller as well as a boost controller. The dimming features are particularly useful in notebook applications.

Working Principle

The BH6048KN-E2 is a Buck Regulator LEDDriver. This type of LED driver is based on a buck topology and it basically provides an efficient way to control the current and voltage of an LED load. A buck regulator is composed of a high side switch, a low-side switch, and a feedback loop. The switches work together to regulate the voltage and current output. Depending on the design of the buck regulator, there may be different components such as diodes, capacitors, and resistors. In the case of the BH6048KN-E2, there are two independentCurrent Regulators that are used to regulate the output and keep it constant. The BH6048KN-E2 also has a dimming control feature, which allows the user to adjust the light intensity of the LED.

The BH6048KN-E2 is a highly efficient device, with an efficiency of up to 96%. It has a wide operating range, an adjustable output voltage, and an adjustable output current. It is designed to be used in applications where the input voltage can vary, ranging from 3V to 20V. It can operate at temperatures ranging from -25°C to +85°C. In terms of safety features, the BH6048KN-E2 has overvoltage protection, thermal shutdown, overcurrent protection, and short-circuit protection.
