The internal switch is rated for 1.5A, so the actual output current depends on the input-to-output voltage ratio and the inductor selection — at a 3.3V input, expect roughly 900 mA continuous output before the switch current limit is reached. The 1.5 MHz switching frequency keeps the inductor and output capacitor physically small, which matters when board area is tight. The synchronous rectifier (a MOSFET replacing the usual Schottky diode) improves efficiency by a few percent across the load range — the extra die area in the 8-DFN package pays back in lower thermal dissipation at 1A output. ## Package and layout considerations The pad is the main heat path — a four-layer board with thermal vias under the pad is the standard layout for full 1.5A switch current at high ambient. The 1.5 MHz switching frequency means the input capacitor should be placed within a few mm of the VIN and GND pins to keep the switching loop small. A 10 µF ceramic input cap with a 6.3V or higher rating is typical; the output capacitor can be 22 µF ceramic for the fixed 5V rail.","metaTitle":"LTC3529EDCB#TRPBF Boost Regulator, 5V Fixed, 1.5A Switch","metaDescription":"Analog Devices LTC3529EDCB#TRPBF step-up boost regulator, fixed 5V output, 1.5A switch, synchronous rectifier, 8-DFN package.

The LTC3529 is a straight step-up — if your design only ever needs to boost from a lower voltage to 5V, the LTC3529 is the correct topology. The ADP2504 handles input voltages above and below the output, so it is not a pin-to-pin drop-in but may cover a wider input range in the same 5V rail application."},{"question":"What compliance documentation does Analog Devices provide for LTC3529EDCB#TRPBF?","answer":"The LTC3529EDCB#TRPBF is ROHS3 compliant.
