The S-8353A00MC-IQPT2U is a new type of DC DC switching regulator released by Seiko, which combines high efficiency, low-cost components, and a wide range of applications. This product is designed to provide voltage regulation and power management solutions for various embedded applications including Industrial, Automotive, and Internet of Things (IoT) devices.

The S-8353A00MC-IQPT2U is a discrete type DC DC switching regulator, which is capable of providing differential output voltages from an external transformer with an integrated power switch. It implements a synchronous buck converter configuration, with a single output voltage which can be switched between 1.2V – 5.5V in 0.1V increments. It is designed to drive up to 10A of output current, and has an adjustable output voltage accuracy of ±0.5%. Additionally, the device features a high frequency operation, which allows for a very low external component count.

The S-8353A00MC-IQPT2U has several features which make it suitable for a wide range of applications. It meets all the requirements of automotive systems, such as 9V – 16V pre-regulation and wide temperature tracking range of -40°C-125°C. In addition, the S-8353A00MC-IQPT2U has Reverse Current Protection (RCP), a unique feature which prevents current flowing backwards and damaging the circuit, and Thermal Protection (TP) which helps protect against thermal overload and short-circuiting.

The S-8353A00MC-IQPT2U also features a PMBus interface which allows for real-time monitoring of the output current, voltage, and temperature. This enables users to proactively monitor the power supply and adjust the output settings accordingly. The wide range of set-up parameters, combined with the PMBus interface, provide a comprehensive solution for system level protection and optimization.

In addition to its features, the S-8353A00MC-IQPT2U is designed to perform within an extremely efficient range of 95% – 97%, making it a great choice for applications where power saving is the main priority. This device also has a low operating temperature range of -20°C – 85°C, making it suitable for even the harshest of environments.

The S-8353A00MC-IQPT2U uses a principle of synchronous buck converter to convert high voltage input power into 12V – 5.5V output. The conversion is achieved by pulsing a high-side switch, which is driven by a switch control signal, to control the switch transition from off to on. As the switch is pulsed, the current through it increases and energy is transferred from the input power source to the output circuit. The output voltage is further regulated by the voltage feedback loop, which consists of an error amplifier and an adjustable reference voltage, ensuring an output voltage within the desired range. The switching frequency of the device is set at 500 kHz, which allows for relatively low output ripple and low component count in the driver circuit.

The S-8353A00MC-IQPT2U is a great choice for embedded applications which require a compact, highly efficient, and cost-effective solution. It offers a full featured, robust, and reliable solution with a wide variety of set-up and monitoring options. The device can also be used in automotive and industrial applications, as well as a wide range of IoT devices.
