ST launches synchronous DC/DC converter for intelligent industrial equipment
Published2020.02.13 10:47PWM mode operation across all loads, minimizes electromagnetic interference
Features Power-Good output pin available for error indication
ST Microelectronics launched the L6983, a highly integrated synchronous 38V/3A DC/DC converter on the 13th.
The L6983 converter maintains maximum efficiency of 95% across all load conditions and integrates on-chip synchronous MOSFETs to reduce the number of external components while simplifying design. Additionally, standby current consumption is only 17µA.
Variant products with low current consumption (L6983C) and low noise (L6983N) characteristics are also available.
The L6983C switches to Pulse-Skipping mode when load current is below 0.6A. The L6983N, suitable for noise-sensitive applications, operates in PWM (Pulse-width modulation) mode across all loads to minimize electromagnetic interference.
The L6983 converter, providing an input voltage range of 3.5V to 38V, is suitable for distributed intelligent nodes such as 2V and 24V industrial bus power supply systems, battery-powered equipment, and smart building controllers, as well as always-on devices including smart sensors. Devices can be selected from 3.3V, 5V, or adjustable output voltage options.
All L6983 series products are equipped with Power-Good output pins that can be used for power-up/power-down sequencing and logic circuit activation or error indication.
Additionally, integrated feedback-loop compensation, overvoltage protection, and Soft-Start circuits simplify power supply system design. Switching frequency can be programmed from 200kHz to 2.2MHz, and EMC regulations can be met through frequency spread spectrum operation and external frequency synchronization.
ST is supporting device selection and power supply development acceleration by launching the evaluation board STEVAL-ISA208V1 for the L6983C. The L6983C and L6983N are currently produced in 3×3mm QFN16 packages, with pricing starting at $1.5 for purchases of 1,000 units or more.
