The MP1540DJ-LF-Z from Monolithic Power Systems is a current mode step-up converter designed for small, low-power applications. It features a fixed switching frequency of 1.3MHz, allowing for the use of tiny, low-cost inductors and capacitors. The device operates with an input voltage range of 2.5V to 6V and can produce an output voltage as high as 18V.
Key features include an integrated power MOSFET, internal soft-start for reduced inrush current, under-voltage lockout (UVLO), current limiting, and thermal overload protection. These features protect the device from damage during output overload conditions and help extend battery life.
The MP1540DJ-LF-Z is available in a compact TSOT-23-5 package, making it suitable for space-constrained designs. Its applications include camera phone flashes, handheld computers, PDAs, digital cameras, external modems, small LCD displays, and white LED drivers.
This step-up converter is designed for surface mount applications and operates within an ambient temperature range of -40°C to +85°C.
