It switches at 120kHz and the internal switch is rated for 1.2A. ## Output voltage range and setting it The output is adjustable from 1.25V up to 9V, with positive output configuration. Setting the voltage is done with an external resistor divider. ## What the 1.2A switch rating means for your load The 1.2A switch current is the peak current the internal transistor can handle. That sets the maximum output power. ## Temperature grade and where it fits Rated for 0°C to 70°C operating temperature — commercial grade. That puts it in indoor equipment, benchtop gear, consumer electronics, or office appliances. Not for under-hood automotive, not for a rooftop telecom enclosure in summer. If your board lives in a conditioned space, this is fine. The through-hole DIP package also means it's a natural fit for prototyping, breadboarding, or repair where you want to socket the part.","metaTitle":"ADP1109AAN Boost Converter IC, 1.2A Switch, 120kHz, 8-DIP","metaDescription":"ADP1109AAN step-up DC-DC converter from Analog Devices.
