The LTC3425EUH is a monolithic, 4-phase synchronous boost converter from Linear Technology, designed for efficient power management in battery-powered applications. It is capable of operating with input voltages as low as 0.5V and can deliver an output voltage up to 5.25V.
The 4-phase architecture enables an effective switching frequency of up to 8MHz, which significantly reduces output ripple current and peak inductor current. This design allows for the use of small, low-profile inductors and ceramic capacitors, even at high load currents. The converter features output disconnect capability and can start up from voltages as low as 0.88V.
This device is housed in a compact 5mm x 5mm QFN-32 package, measuring only 0.8mm in height. It operates within a temperature range of 0°C to 85°C. Key features include constant frequency current mode control, external synchronization, and a power good signal.
The LTC3425EUH is suitable for various applications requiring efficient voltage step-up conversion, such as portable electronics, point-of-load regulation in low-voltage systems, and battery-powered devices.
The input voltage range is 0.5V (minimum) to 4.5V (maximum), with a startup minimum of 0.88V.
The output voltage is adjustable from 2.4V (minimum) to 5.25V (maximum).
