The 2V minimum is the start-up voltage — below that the oscillator won't run. At the upper end, 9V is the absolute limit on the input pin; feeding it 12V will damage the switch. For battery-powered designs, the 2V floor lets you drain a 2-cell alkaline pack nearly to empty before the converter drops out. The 9V max also means you cannot use this part to regulate from a 12V rail down to 12V — that's a different topology. ## Sourcing and availability The ADP1109AN-12 is an active, in-production part from Analog Devices. It is sourced through independent distribution and quoted to order against an RFQ. Current pricing and availability are confirmed at quote time — no stock figures or lead-time numbers are published here. For BOM qualification, the active lifecycle means no imminent EOL risk, but the RoHS non-compliance may drive a future redesign if your compliance requirements tighten. If you need a RoHS-compliant boost converter in a similar DIP package, the ADP1111 family is a functional alternative (see FAQ).","metaTitle":"ADP1109AN-12 Step-Up DC-DC Converter, Fixed 12V Output","metaDescription":"ADP1109AN-12 boost converter from Analog Devices.

The continuous output current depends on input voltage and efficiency; from 5V in to 12V out, expect approximately 300 mA maximum."},{"question":"What is the equivalent of ADP1109AN-12?","answer":"A functional alternative is the ADP1111ANZ-5, which can be configured as a boost converter with a fixed 5V output. It operates at 72kHz and has a 0.4A switch, so it delivers less output current. The ADP1111 family also supports step-down (buck) topology, which the ADP1109 does not. For a closer match in output voltage, the ADP1111 adjustable version can be set to 12V with external resistors."},{"question":"What is the pinout of ADP1109AN-12?","answer":"The ADP1109AN-12 uses a standard 8-pin DIP package (8-DIP, 0.300\" row spacing). The pin functions are: Pin 1 (SW1), Pin 2 (SW2), Pin 3 (GND), Pin 4 (FB), Pin 5 (VIN), Pin 6 (SHDN), Pin 7 (VSW), Pin 8 (ILIM).
