LTC3529EDCB#TRMPBF

LTC3529 is a 5V output, synchronous, fixed frequency step-up DC/DC converter optimized for USB On-The-Go (OTG) hosting applications. USB OTG-specific features include a fault flag with 22ms deglitching to indicate when the bus is overloaded, output disconnect and short-circuit protection. Following a fault, this device can be programmed to either latch off or restart after a time-out duration. Additional features include a <lt/>1μA shutdown mode, soft-start, inrush current limiting and thermal overload protection. Anti-ring circuitry reduces EMI during low power operation. It is widely used in application such as personal media players, digital video cameras, digital multimedia broadcast tuners, digital cameras, smart phones etc.
