Microchip Technology, Inc. LED Drivers MIC3231YTSE-TR

The MIC3231YTSE-TR is a constant current boost controller designed for driving high power LEDs, with an input voltage range of 6V to 45V and capable of delivering up to 70W. It features programmable LED drive current and a feedback voltage of 250mV ¬±3%, ensuring accurate performance. The device supports PWM dimming and includes an enable shutdown function for low power operation. It also offers frequency synchronization with other MIC3230 devices, allowing for reduced noise in multi-device configurations. Protection features include over voltage protection (OVP), thermal shutdown, and under-voltage lock-out (UVLO). The MIC3231 incorporates a dither feature to minimize electromagnetic interference (EMI), making it suitable for sensitive applications. It is available in a 16-pin EPAD TSSOP package and operates within a junction temperature range of -40¬8C to +125¬8C. This product is ideal for applications such as street lighting, solid state lighting, and general illumination.
