It handles an input range of 3.5V to 36V, making it useful for systems that need to regulate down from a 12V or 24V intermediate bus without an extra pre-regulator. Both outputs are positive and fixed — no external resistor divider needed to set the voltage. The part switches between 1MHz and 2.2MHz, which keeps the inductor and capacitor values small enough for a compact PCB layout. ## Synchronous rectification and thermal envelope The internal synchronous rectifier means the low-side MOSFET is on-die, so you skip the external Schottky diode that older buck converters need. That saves a component and a bit of board area, and it keeps the efficiency curve flatter across load. That footprint is common enough that a layout engineer can drop it into an existing pad stack for a 4x4 QFN without re-spinning the board. ## Active lifecycle and compliance RoHS3 compliant — the '+' suffix in the order code confirms lead-free and halogen-free construction per the manufacturer's marking scheme.","metaTitle":"MAX17233ETIR+ Buck Regulator, 3.3V/5V Fixed, 28-TQFN","metaDescription":"Active dual-output step-down regulator from Analog Devices. 3.5V-36V input, 3.3V/5V fixed outputs, 1-2.2MHz switching, -40 to +85°C.
