AS1110-BSSU

PMIC - LED Drivers

AS1110-BSSU is a state-of-the-art high efficiency, low temperature rising, constant current, quasi-resonant drive, and SSM (semiconductor self-protected) step-down switching mode power supply (SMPS) DC/DC converter.The core of the AS1110-BSSU is the PWM (pulse width modulation) controller, which is integrated with the burst mode control, single loop compensation and two switch buffers. The PWM control can achieve excellent efficiency and low temperature rising even at light load conditions. The built-in SSM technology helps to reduce the power losses and also to provide some surge protection.The built-in synchronous rectification switch and an external gate driver reduce the power losses and also provide excellent efficiency. The external gate driver also provides a programmable steering capability.The AS1110-BSSU is designed for applications such as LED lighting, automotive, telecommunications and consumer electronics.The AS1110-BSSU does not require any external components for controlling the output current. The device is designed for use with fluorescent and LED light sources, with a wide range of dimming settings. The dimming range is 0-120 Hz.The current sense resistor is used to reduce the output voltage ripple and to improve the LED light source stability. The LED light source can be dimmed as desired, with the dimming range being adjustable.The AS1110-BSSU also provides protection against common-mode faults such as over voltage, over current and reverse polarity.The AS1110-BSSU is a highly reliable and robust device. Its built-in self-protection technology ensures that it meets the industry performance standard and provides safe operation even under the most rigorous conditions.The long-term reliability of the AS1110-BSSU is also improved by the use of high temperature rated components. The device is certified to meet the RoHS (Restrictive of Hazardous Substances) requirements.Overall, the AS1110-BSSU demonstrates excellent performance in terms of efficiency, temperature rising and current protection. It is a robust device with low power loss and extremely low heat dissipation. It is suitable for applications such as LED lighting, automotive, telecommunications and consumer electronics.
