ST’s monolithic switching regulators offer input-voltage capability up to 61 V, deliver output currents up to 4 A, with high switching frequency.
This broad portfolio of ICs is composed of highly-specialized products to meet every market requirement: HV technology together with high reliability and robustness for industrial and automotive applications, compactness, high efficiency at any load and a high level of performance for consumer and computer products.
These devices embed a full set of protection functions (overcurrent, overvoltage, over-temperature) to increase the MTBF and reduce the number of external components.
There are multiple package options, all offering compactness and high thermal performances to fit different applications.

Large selection of step-down DC-DC regulators with synchronous rectification
In the quest for higher efficiency and compact form factor in their DC-DC supply designs, engineers now have a few more allies: the L6985F, L6986F and L6986 step-down DC-DC regulators with synchronous rectification and an output current of 0.5 A, 1,5 A and 2 A respectively.
Based on a peak current mode architecture with a p-channel power MOSFET, they feature a selectable low-consumption-mode (LCM burst mode) to increase efficiency at light load, and a low-noise-mode (LNM with fixed PWM switching frequency) for noise-sensitive designs.
An easy-to-use evaluation board (STEVAL-ISA156V1) based on the L6986 regulator is available to help you configure and evaluate application parameters so you can reach higher efficiency, higher power density and lower standby power designs.
