Suitable for applications such as battery power systems and portable measuring instruments

Analog Devices has released the new LTC7124, a high-efficiency 4 MHz synchronous dual-output buck regulator with a fixed frequency, peak current mode architecture.

The new product also includes spread-spectrum modulation options to reduce radiated and conductive EMI noise. The LTC7124 supplies a continuous output current of up to 3.5A from each channel or generates a two-phase single output of up to 7A through a package with a compact 3mm x 5mm footprint.

The LTC7124 operates with input voltages ranging from 3.1V to 17V and provides a wide output voltage range from 0.6V to 99% of VIN with high VOUT accuracy of ±1%, making it ideal for 1-4 cell lithium-ion battery applications as well as 5V to 12V intermediate bus systems. Additionally, it is suitable for applications such as battery power systems, point-of-load (POL) power supplies, portable instruments, and handheld scanners.

The LTC7124 can be configured to perform forced continuous operation, which reduces supply ripple and potential RF interference. In addition, it supports various features such as input overvoltage and overtemperature protection, PowerGood voltage monitoring, independent soft-start functions per channel, internal or external loop compensation, and programmable current limiting and short-circuit protection.
