STCF01PMR Integrated Circuits (ICs)

PMIC is an acronym for Power Management Integrated Circuit (PMIC). LED drivers are a type of PMIC that are used to control LED lighting for a variety of applications. STCF01PMR is a PMIC - LED driver that provides consistent and reliable power to LEDs in a number of applications.

STCF01PMR Application Field

STCF01PMR is a wide-operating power supply designed for LED lighting. It can operate with high voltage supply, up to 72V and high LED chain current, up to 100mA/channel. STCF01PMR is suitable for LED lighting applications that require multiple strings of LEDs, such as general lighting, signage, automotive, and decoration.

The operating temperature range of the STCF01PMR is from -40℃ to 125℃. This wide operating temperature range allows the STCF01PMR to be used in harsh environments, such as automotive and outdoor applications. It also has a high power efficiency (>90%) which means that it can provide a stable power supply with very little heat output.

STCF01PMR Working Principle

The working principle of the STCF01PMR is based on the constant output current provided by the pulse-width-modulation (PWM) control. The PWM control enables the STCF01PMR to maintain a constant output current regardless of the input voltage, the ambient temperature, and the number of LEDs in the string.

The STCF01PMR uses a built-in constant current timer to generate the proper PWM control signal. The timer is programmed to generate a PWM signal, which maintains a constant average current across the LED string. In addition, the STCF01PMR also uses an LED current binning feature which can be used to set different LED current levels for each LED string.

The STCF01PMR also features a wide voltage range which enables it to work with different power sources. The STCF01PMR can accept input voltages from 10V to 72V. This wide range makes it possible to use different sources, such as AC/DC power supplies, DC/DC converters or batteries.

Conclusion

The STCF01PMR is a versatile PMIC - LED driver, suitable for a wide range of applications. It has a wide operating temperature range and high power efficiency, making it suitable for harsh environments. In addition, the STCF01PMR also features a wide input voltage range and a built-in constant current timer which provides a constant output current. This makes the STCF01PMR the perfect solution for LED lighting applications that require multiple strings of LEDs.
