MIC3223YTSE Description

Short technical summary and product information.

The MIC3223YTSE from Micrel Inc. is a constant current boost LED driver designed for high power LED applications. It features a peak current mode control PWM boost regulator with an operating input voltage range of 4.5V to 20V, suitable for 5V or 12V bus applications. The device can achieve step-up output voltage conversion up to 37V and implements a fixed internal 1MHz switching frequency to minimize design footprint.

 

Key electrical characteristics include a 200mV feedback voltage with ±5% accuracy and an internal 100mΩ/3.5A power FET switch. The MIC3223YTSE supports LED dimming via a PWM signal and includes an enable pin for low power shutdown. Protection features are integrated, such as output over-voltage protection (OVP), thermal shutdown, switch current limiting, and under-voltage lockout (UVLO).

 

This LED driver is offered in a low profile exposed pad 16-pin TSSOP package, suitable for surface mount applications. Its robust design makes it ideal for various solid-state illumination applications including general lighting, bulb replacement, and garden pathway lighting.
