The internal switch is rated for 1.2 A. ## 1.2 A switch current — what it means for your load The 1.2 A switch current rating is the peak current the internal NPN switch can handle cycle-by-cycle. ## Sourcing this part The ADP1109AAN-3.3 is an active, RoHS-non-compliant boost converter in a through-hole DIP package. It is sourced through independent distribution channels and quoted to order against an RFQ.","metaTitle":"ADP1109AAN-3.3 Step-Up DC-DC Converter, 3.3V Fixed Output","metaDescription":"ADP1109AAN-3.3 boost converter from Analog Devices, fixed 3.3V output, 1.2A switch, 2V-9V input, 120kHz switching, 8-DIP through-hole package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Bulk","Function":"Step-Up","Topology":"Boost","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Current - Output":"1.2A (Switch)","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"120kHz","Operating Temperature":"0°C ~ 70°C","Synchronous Rectifier":"No","Voltage - Input (Max)":"9V","Voltage - Input (Min)":"2V","Supplier Device Package":"8-PDIP","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.44","stockQuantity":0,"priceTiers":[{"qty":687,"price":"$0.44000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/jf0dcs0dwj/ANDIS07013-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to ADP1109AAN-3.3?","answer":"For a RoHS-compliant through-hole alternative with similar boost function, the ADP1111ANZ-5 offers a fixed 5 V output but also supports step-down topology and has a lower 0.4 A switch current. For higher output current (2.5 A switch) in a surface-mount package, the LT1305CS8#PBF is a boost-only part with fixed 5 V output. The ADP1111ARZ is an adjustable-output surface-mount part with 0.4 A switch and both buck and boost capability. None are drop-in pin-compatible — each requires a layout review."},{"question":"Is ADP1109AAN-3.3 RoHS compliant?","answer":"No, the ADP1109AAN-3.3 is marked RoHS non-compliant. It contains lead (Pb) above the 0.1% threshold and is not suitable for RoHS-required assemblies without an exemption."},{"question":"What is the pinout of ADP1109AAN-3.3?","answer":"The ADP1109AAN-3.3 uses a standard 8-DIP (0.300\", 7.62 mm) package. The pinout follows the typical boost converter arrangement: VIN, GND, SW (switch output), FB (feedback — internally fixed for 3.3 V), and SHDN (shutdown).
