The BD93942F-GE2 is a power management integrated circuit (PMIC) used in the field of LED drivers. It is a highly efficient, low voltage step-down controller pre-loaded with IOFF-OCP function and an independent over-temperature protection circuit. With an input voltage of up to 32V, it can supply 5A/40W of continuous current. This provides reliable regulation and high efficiency switching without the need for external parts.The BD93942F-GE2 is mainly used in lighting control applications, such as linear and point-source lighting fixtures, backlighting systems and patterned illumination. It is also suitable for portable electronic devices such as tablets, laptop PCs and thin film electronics. The device is also suitable for automotive applications, including headlights, exterior lighting, interior lighting and vehicle infotainment displays.The BD93942F-GE2 works using a high-efficiency, current-mode PWM control loop. The constant off-time control reduces power losses by providing a stable output voltage with fast load current changes. The output voltage is regulated by sensing the voltage at the switching node and is programmable over a 215mV to 6.5V range. This makes the device suitable for many different output voltages from input voltages ranging from 4.5V to 32V.The device also contains other protective features, including safety functions which will shut down the output voltage in the event of over current or over temperature conditions. There is also an adjustable soft start time, to stop over current conditions resulting in the LED nodes during start-up. The device also features an under voltage lockout and over temperature protection, to protect devices using the BD93942F-GE2 from damage.In conclusion, the BD93942F-GE2 is an ideal power management solution for LED driver applications that require high efficiency and reliable regulation. Its wide input and output voltage range make it well suited for applications such as automotive headlamps, interior lighting, backlighting, point-source lighting fixtures, patterned illumination and consumer electronics. Its wide range of protective features ensures that the devices it powers remain safe from over current and over temperature conditions, while its constant off-time control reduces power losses and provides a stable output voltage with fast load current changes.
