MBI6662 is a high efficiency, constant current and step-down DC/DC converter. Itis designed to deliver constant current to light up high power LEDs. With the adaptive hysteretic PFM control scheme, MBI6662 can achieve constant frequency operation under common anode connection. The output current of MBI6662 can be set by an external resistor, and LED brightness can be controlled via a pulse width modulation (PWM) signal through DIM pin. In addition, the soft-start function limits the inrush current while the
power is turned on. MBI6662 also features under voltage lock out (UVLO), over temperature protection (OTP), and
over current protection (OCP) to ensure system robustness and prevent IC and LEDs from being damaged once any abnormal condition occurs. To ensure system reliability, MBI6662 is equipped with thermal shutdown protection (TSD), which protects IC from overheating by turning off the internal MOSFET. MBI6662 is available in thermal-enhanced DFN-10 and SOP-10 package to handle power dissipation more efficiently.
