The MIC2601 is a PWM DC/DC boost switching regulator designed for high power density applications, featuring an internal switch rated for 40V and 1.2A. It operates at a frequency of 1.2MHz, allowing for compact design with small external components. The input voltage range is from 4.5V to 20V, and the output voltage can be adjusted up to 40V. The device includes features such as programmable soft start, output over-voltage protection, and under-voltage lockout (UVLO). It has a low shutdown current of less than 10¬µA and operates within a junction temperature range of -40¬8C to +125¬8C. The MIC2601 is suitable for applications including multimedia set-top boxes, broadband communications, and local boost regulation.
The MIC2601/2 is a 1.2MHz/2MHz, PWM DC/DC boost switching regulator. High power density is achieved with the MIC2601/2's internal 40V/1.2A switch, allowing it to power large loads in a tiny footprint.
The MIC2601/2 implements constant frequency 1.2MHz/2MHz PWM current mode control. The MIC2601/2 offers internal compensation that provides excellent transient response and output regulation performance. The high frequency operation saves board space by allowing small, low-profile external components. The fixed frequency PWM scheme also reduces spurious switching noise and ripple to the input power source.
Soft start reduces in rush current and is programmable via external capacitor.
The MIC2601/2 has an operating junction temperature range of -40°C to +125°C.
