The Analog Devices LTC3119HFE#TRPBF is a high-efficiency, 18V monolithic buck-boost converter capable of delivering up to 5A of continuous output current. Its proprietary 4-switch PWM architecture ensures seamless operation across input voltages that are above, equal to, or below the output voltage.
This converter supports a wide input voltage range from 2.5V to 18V, with operation possible down to 250mV after start-up. The output voltage is adjustable and can range from 0.8V to 18V. It offers a programmable switching frequency between 400kHz and 2MHz, and can be synchronized with an external clock up to 2MHz.
Key features include output short-circuit protection, thermal overload protection, low shutdown current (less than 3µA), power good indicator, Burst Mode operation, and maximum power point control. The LTC3119HFE#TRPBF is supplied in a thermally enhanced 28-lead 4mm × 5mm QFN and TSSOP packages, with this specific part number indicating the 28-TSSOP package with an exposed pad.
Applications for this converter include wide input range power supplies, 1- to 4-cell lithium battery powered products, RF power supplies, solar battery chargers, system backup power supplies, and lead-acid to 12V regulators.
