LT3758AIMSE#PBF, DC/DC Controller, Boost/Flyback/ Inverting/SEPIC, 5.5 to 100 V, 1 MHz, -40 to 125 °C, MSOP-EP-10

Полупроводники - Микросхемы\Микросхемы Управления Питанием\DC - DC Устройства Управления Питанием\DC - DC КонтроллерыLT3758A is a wide input range, current mode, DC/DC controller which are capable of generating either positive or negative output voltages. They can be configured as either a boost, flyback, SEPIC or inverting converter. The LT3758A drive a low side external N-channel power MOSFET from an internal regulated 7.2V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of LT3758A can be set with an external resistor over a 100kHz to 1MHz range, and can be synchronized to an external clock using the SYNC pin. A minimum operating supply voltage of 5.5V, and a low shutdown quiescent current of less than 1µA, make the LT3758A ideally suited for battery powered systems. The LT3758A feature soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. The LT3758A has improved load transient performance compared to the LT3758. • Wide input voltage range from 5.5V to 100V• Positive or negative output voltage programming with a single feedback pin• Current mode control provides excellent transient response• Programmable input under voltage lockout with hysteresis• Programmable soft-start• 10-lead (3mm × 3mm) plastic MSOP package• Operating temperature range from -40°C to 85°C
