S-8353A27MC-IQMT2G is a high-efficiency DC/DC synchronous step-down converter from ROHM, which has a wide operational voltage range from 2.500 V to 5.500 V and is provided in a 15-pin Power3S (Small Size System Power Supply) package. The product delivers an output current of up to 1A, making it suitable for a variety of devices such as industrial personal computers, automation equipment, servers, etc. It features adjustable switching frequency, thermal shutdown protection, built-in soft start function, output voltage tracking function and Under Voltage Lock Out (UVLO) protection, allowing it to provide stable output voltage even if the input voltage fluctuates.

The S-8353A27MC-IQMT2G operates according to the (multiphase interleaving) synchronous rectification principle. This principle is based on the concept of connecting several synchronous rectifiers (SR) arrays in parallel such that the current divide in each SR array and the ripple current is reduced. In this case, the SR arrays are connected in an interleaving manner with each SR array operating on different voltage nodes. This reduces the load on each of the SR arrays and allows for better efficiency, lower output impedance and higher output power.

The S-8353A27MC-IQMT2G is typically used in applications such as industrial personal computers, automation equipment, servers, and other applications which require a wide input voltage range and stable output voltage. It is also suitable for applications that are sensitive to output noise, such as systems with sensitive radio frequencies or data communication protocols.

The S-8353A27MC-IQMT2G is part of a family of PMIC – Voltage Regulators – DC DC Switching regulators that ROHM offers, which are optimized for a variety of applications. This family provides users with the flexibility to select the right solution for their application by offering products with different output currents, switching frequencies and temperature ranges. The working principle of these devices is based on synchronous rectification and current share, allowing them to be more efficient and less noisy than conventional switching power supplies.
