LTC3421EUF#PBF Analog Devices Inc.
Analog Devices Inc.
Analog Devices (NASDAQ: ADI) leads in crafting high-performance analog, mixed-signal, and digital signal processing integrated circuits. For decades, they've tackled signal processing challenges across global electronics. With over 100,000 clients, their products convert real-world phenomena into electrical signals. Merged with Maxim Integrated, they offer top-tier mixed-signal and power management technologies, solving complex problems from DC to 100 GHz and sensor to cloud.
View All Product from Analog Devices Inc.The LTC3421EUF is a high efficiency, current mode, fixed frequency, step-up DC/DC converter with true output disconnect and inrush current limiting. The device includes a 0.10Ω N-channel MOSFET switch and a 0.14Ω P-channel synchronous rectifier. This product has the ability to simply program the output voltage, switching frequency, current limit, soft-start, Burst Mode threshold and loop compensation with external passive components.
Quiescent current is only 12µA during Burst Mode operation, maximizing battery life in portable applications. The oscillator frequency can be programmed up to 3MHz and can be synchronized to an external clock applied to the SYNC pin. An open-drain uncommitted low-battery comparator is included. The part maintains operation in applications with a secondary cell powering the output voltage during shutdown.
Other features include: 1µA shutdown, anti-ringing control, thermal limit and reference output.
The LTC3421EUF is available in a small 4mm × 4mm QFN package.
