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.
