The LTC3119EFE#PBF is a high-efficiency, 18V monolithic buck-boost DC-DC converter from Linear Technology (LT) capable of delivering up to 5A of continuous output current. This converter utilizes a proprietary 4-switch PWM architecture for seamless operation across input voltages above, equal to, or below the output voltage.
Key electrical specifications include a wide 2.5V to 18V input range and an adjustable output voltage from 0.8V to 18V. It supports switching frequencies from 400kHz to 2MHz, with synchronization capabilities to an external clock up to 2MHz. The device can operate with input voltages as low as 250mV after start-up.
Packaged in a 28-pin TSSOP, the LTC3119EFE#PBF is designed for applications requiring compact solutions. Its extensive feature integration and low-resistance internal power switches minimize the overall solution footprint. Applications include wide input range power supplies, 1 to 4 cell lithium battery powered products, RF power supplies, solar battery chargers, and system back-up power supplies.
Operating temperature ranges from -40°C to 125°C. The device offers features such as accurate run comparator threshold, output short-circuit protection, and thermal overload protection.
The input voltage range is from 2.5V to 18V.
The output voltage can be adjusted from 0.8V to 18V.
The maximum output current is 5A in buck mode (VIN > 6V).
The switching frequency can be set between 400kHz and 2MHz.
The operating temperature range is -40°C to 125°C.
It is supplied in a TSSOP-28 package.
