XL1509-3.3 AI Analysis:
Datasheet, Specs, Alternatives & ECAD

The device includes built-in thermal shutdown, current limiting, and a second current limit function that reduces the switching frequency to 50 kHz under overload conditions.

Review the layout guidelines, specifically the placement of input capacitors near pins 1 and 5-8, and ensure the Schottky diode is correctly positioned to prevent switching noise.

Key specs include a 4.5V-40V input range, 3.3V fixed output, 2A output current, 150 kHz switching frequency, and an operating temperature range of -40°C to 125°C.

The part is widely available in the market, but users should verify current stock levels and lead times with distributors for high-volume production.
