DESCRIPTION
1.5A, 1.5MHz Step-Up
DC/DC Converter in
2mm
× 3mm DFN
The LTC3529 is a 5V output, synchronous, xed 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 pack-
age. The LTC3529 can operate from input voltages as low
as 1.8V.
USB OTG-specic features include a fault 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 latchoff 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.
