Hot-selling and scarce ADP1611ARMZ-R7 20 V,1.2 MHz Step-Up DC-to-DC Switching Converter MSOP-8 spot stock

Product Descriptions

The ADP1611 is a step-up dc-to-dc switching converter with anintegrated 1.2 A, 0.23 Ω power switch capable of providing anoutput voltage as high as 20 V. With a package height of lessthan 1.1 mm, the ADP1611 is optimal for space-constrainedapplications such as portable devices or thin film transistor(TFT) liquid crystal displays (LCDs).

The ADP1611 operates in pulse-width modulation (PWM)current mode with up to 90% efficiency. Adjustable soft startprevents inrush currents at startup. The pin-selectable switchingfrequency and PWM current-mode architecture allow excellenttransient response, easy noise filtering, and the use of small,cost-saving external inductors and capacitors .

The ADP1611 is offered in the Pb-free 8-lead MSOP andoperates over the temperature range of −40°C to +85°C .
