LT8615 Monolithic Step-Down Switching Regulators

Introduction

The LT8615 Monolithic Step-Down Switching Regulators from Analog Devices Inc. are designed to provide high efficiency and low electromagnetic interference (EMI) in compact applications. These regulators are particularly suitable for environments where low EMI emissions are critical, making them an excellent choice for both industrial and automotive applications.

Part Description

The LT8615 regulators feature a synchronous design that allows for efficient power conversion with a quiescent current of just 2.5µA in burst mode. This low quiescent current ensures high efficiency even at low load currents, while the output ripple is maintained below 10mVP-P. The device operates over a wide input voltage range of 3V to 42V and supports adjustable switching frequencies from 400kHz to 2.5MHz. With a fast minimum switch-on time of 40ns and a very low dropout voltage of 125mV at 1A, the LT8615 is engineered for performance. It comes in a compact 3mm x 3mm side wettable QFN package, making it ideal for space-constrained designs.
