The S-8356K30MC-NEPT2G is a DC-to-DC step-up switching controller for applications such as USB power supply and PMIC. Developed in response to a consumer need for highly efficient power supply designs, this product helps designers create advanced DC-to-DC step-up solutions with low quiescent current, high efficiency, and fast load transient response. The product has a wide input voltage range of 3.3V to 24V and can drive up to 8A continuous load current with integrated high-side and low-side MOSFETs.

The S-8356K30MC-NEPT2G switching controller features a programmable operating frequency up to 2MHz, and an adjustable soft-start function to ensure smooth start-up overshoot. It also features adjustable peak current limit and adaptive slope compensation to reduce system component cost and ensure stability over a wide DC input voltage range. In addition, the device integrates an internal compensation and loop amplifier block, enabling designers to use the S-8356K30MC-NEPT2G as a standalone solution for voltage applications up to 24V.

The S-8356K30MC-NEPT2G is available in an industry-standard 8-pin SOIC package. It is also 100% RoHS compliant and lead-free, making it a reliable choice for power supply designs.

Working Principle of S-8356K30MC-NEPT2G

The S-8356K30MC-NEPT2G works by controlling an internal switch to regulate the output voltage. This switch is connected between the input voltage source and the output current source, and is driven by an internal oscillator to switch between the two sources. When the switch is on, current flows through the internal switch and the output voltage is regulated according to the feedback signal. When the switch is off, the output current source is shut off and no current flows through the switch.

When the input voltage is too high or too low, the S-8356K30MC-NEPT2G reacts by controlling the switch on and off in order to maintain the output voltage within a given range. The switching frequency can be adjusted for different input and output conditions, providing additional protection for the load.

The S-8356K30MC-NEPT2G also has a built-in soft-start function, which prevents inrush current from damaging power supplies and load components. The soft-start also smoothes out the start-up process, reducing the risk of output voltage overshoot.

S-8356K30MC-NEPT2G Application Field

The S-8356K30MC-NEPT2G can be used in a wide range of applications such as USB power supply, Power Management Integrated Circuits (PMICs), battery chargers, and display panel power supplies. It is ideal for applications requiring high efficiency and fast transient response.

The wide input voltage range, low quiescent current and programmable frequency of up to 2MHz make the S-8356K30MC-NEPT2G a perfect choice for mobile applications, where space and power are limited. The device is also RoHS compliant and lead-free, providing designers with a reliable, cost-effective solution.
