The LTC3445EUF#TRPBF is a versatile power management IC from Analog Devices / Maxim Integrated, combining a high-efficiency synchronous buck regulator with two LDO regulators and a PowerPath controller. This device operates within a 2.5V to 5.5V input voltage range, making it suitable for single Li-Ion battery applications.
The buck regulator offers a programmable output voltage from 0.85V to 1.55V and can deliver up to 600mA of output current. It operates at a constant 1.5MHz frequency or can utilize a spread spectrum option for reduced noise. The two LDO regulators each provide up to 50mA of output current with a low dropout voltage of 0.3V.
Control is managed via an I2C interface, allowing for standard (100kHz) or fast mode (400kHz) communication. This interface also enables programmable output voltage slew rates. The device is housed in a compact 24-lead (4mm x 4mm) QFN package, suitable for surface mount applications.
Key features include high efficiency up to 93%, dynamic VCC BATT regulation, and low supply current. The LTC3445EUF#TRPBF is ideal for portable instruments and microprocessor supply applications.
