Voltage Regulators - DC DC Switching Regulators datasheet and documents for LT8653SIV#PBF

LT8653SIV#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT8653SIV#PBF is a dual-channel, synchronous step-down Silent Switcher 2 regulator from Analog Devices Inc. It features an input voltage range of 3V to 42V and provides two independent non-isolated outputs with fixed voltages of 3.3V and 5V. Each channel delivers up to 2A of output current. The device operates at a switching frequency of 2MHz and utilizes the Silent Switcher 2 architecture for low EMI performance. It is housed in a 20-TFQFN package with an exposed pad.
