Product Details
The LTC3529 is a 5V output, synchronous, fixed frequency step-up DC/DC converter optimized for USB On-The-Go (OTG) hosting applications. This compact USB OTG 5V VBUS converter features a 1.5MHz switching frequency, internal compensation and a tiny 2mm × 3mm DFN package. The LTC3529 can operate from input voltages as low as 1.8V.
USB OTG-specific features include a fault fl ag with 22ms deglitching to indicate when the bus is overloaded, output disconnect and short circuit protection. Following a fault, the LTC3529 can be programmed to either latch-off or restart after a time-out duration.
Additional features include a <1μA shutdown mode, soft-start, inrush current limiting and thermal overload protection. Anti-ring circuitry reduces EMI during low power operation. The LTC3529 is offered in an 8-Lead 2mm × 3mm × 0.75mm DFN package.
