The LTC3450EUD is a complete power converter solution from Linear Technology (LT) designed for small thin-film transistor (TFT) liquid crystal display (LCD) panels. It operates from a single Lithium-Ion cell, 2- to 3-cell alkaline input, or any voltage source between 1.5V and 4.6V.
This device features a synchronous boost converter that generates a low-noise, high-efficiency 5.1V, 10mA supply. Internal charge pumps are utilized to generate additional voltages of 10V or 15V, and -5V, -10V, or -15V. The output sequencing is controlled internally to ensure proper initialization of the LCD panel. With better than 90% efficiency and low output ripple of less than 5mVp-p, the LTC3450EUD offers a complete 1mm component profile solution.
The LTC3450EUD is available in a low profile (0.75mm), 3mm x 3mm 16-pin QFN package, minimizing solution profile and footprint. A master shutdown input reduces quiescent current to less than 2µA and actively discharges each output for rapid turn-off of the LCD panel. It operates with low noise and fixed frequency operation, and includes a frequency reduction input for high efficiency in blank mode. The ultralow quiescent current is 75µA (Typ) in scan mode.
Applications for the LTC3450EUD include cellular handsets with color displays, handheld instruments, and PDAs. The controlled power-up sequence ensures reliable operation for AVDD/VGL/VGH outputs.
The device accepts an input voltage ranging from 1.5V to 4.6V.
It is housed in a 16-pin QFN package measuring 3mm by 3mm with a height of 0.75mm.
The component operates reliably between -40°C and 85°C.
The quiescent current drops below 2µA when the device is in shutdown mode.
The output ripple remains below 5mV peak-to-peak under normal operation.
It supplies 5.1V for AVDD, 15V for VGH, and -10V for VGL.
