The S-8358B26MC-NQLT2G is a DC/DC switching controller device within the suite of power management integrated circuits (PMIC) available from Toshiba. It is a part of the “Voltage Regulators/DC/DC Switching Controllers” sub-category of PMIC’s, which allow users to control and optimize the power supply in their systems, while providing the components with efficient power sources.

This S-8358B26MC-NQLT2G device is an adjustable frequency DC/DC switching controller optimized to provide the best response time and system performance. The device contains advanced functions such as a high-resolution adjusting voltage detection circuit, an adjustable operating frequency, a 2-phase synchronized control method, and high speed gate control.

It is suitable for a variety of applications including portable and automotive power supply systems, especially for DC/DC converter start-up applications. It can also be used in step-down, step-up, and buck-boost systems. The ultra-small 7-pin x 0.8mm STQFN-L37 package has been designed to provide the best electrical and thermal designs, while minimizing the effects of noise and EMI.

The operating principle of the S-8358B26MC-NQLT2G is based on a synchronous buck converter, which is the most commonly used switching converter design. The converter operates in two modes at each clock cycle to reduce power dissipation and increase efficiency. During the first mode of operation, the high-side switch is turned on and current flows from the input source to the output inductor. During the second mode of operation, the low-side switch is turned on, allowing current to flow from the output inductor to the output load.

The S-8358B26MC-NQLT2G also incorporates a number of features which help the user to optimize the power supply in their systems. This includes a DPPM algorithm for faster transient response, pulse-by-pulse current limit, programmable slew rate control, internal Power-On Reset, and an adjustable operating frequency (200kHz to 1.2MHz). The device also provides an adjustable output voltage with a maximum value of 25V.

The S-8358B26MC-NQLT2G is an advanced DC/DC switching controller device, which provides the user with a versatile platform for optimizing the power supply in their design. It incorporates advanced features such as a high-resolution voltage detection circuit, adjustable operating frequency, and a 2-phase synchronous control method. It also has a compact physical package, allowing it to fit into even the most space-constrained system designs. The S-8358B26MC-NQLT2G is a great solution for high-efficiency power supply designs and is an optimal choice for applications such as portable and automotive power supply systems.
