S-8356Q53MC-OVMT2G is an advanced DC-DC switching controller for industrial applications, specifically designed for use in a wide range of applications requiring high power density and performance. Developed by ROHM Semiconductor, the device features an advanced automatic speed control (AASC) mode that allows it to operate with a wide input voltage range and low quiescent current in order to provide improved power-save performance.
Features
The S-8356Q53MC-OVMT2G is a 5V/3.3V/1.8V DC-DC converter and its features include:
- Built-in over-current, over-voltage, and under-voltage protection
- Input voltage range: 4.5V-20V
- Output voltage range: 0.6V to 5V
- High-efficiency conversion of wide-ranging input supply voltages
- Automatic speed control mode for improved power-save performance
- Low quiescent current
- High power density
Application Fields
The S-8356Q53MC-OVMT2G is ideal for use in industrial applications, such as power supplies, industrial motor controllers, light-emitting diode (LED) lighting, motor drives, and system protection. The controller is also well-suited for use in medical devices, consumer devices, automotive systems, and any application that requires an extremely high efficiency DC-DC converter.
Working Principle
The S-8356Q53MC-OVMT2G utilizes a variable hysteresis current mode control that is composed of voltage error amplifier, a center gap voltage compensation, and a current limiting PWM comparator. This system operates with a programmable switching frequency and employs a core voltage control loop that ensures very accurate regulation of the output voltage.
The device also features an automatic speed control (AASC) mode that enables it to operate with a wide input voltage range, as well as with a low quiescent current. This mode ensures optimal performance across different input voltage ranges and allows for an improved power-save performance. The controller also features a built-in current limiting functionality to protect it against over-current in case an abnormal load current occurs.
Conclusion
The S-8356Q53MC-OVMT2G DC-DC switching controller is an ideal choice for industrial applications that require a wide input voltage range and low quiescent current. The advanced AASC mode enables the device to improve power-save performance while also eliminating the need for external components such as shunts or feed-forward capacitors. The built-in over-current, over-voltage, and under-voltage protection ensure maximum system reliability.
