S-8521B18MC-ATDT2U is a DC/DC switching controller from the Voltage Regulator category in the Power Management IC (PMIC) world. It is designed to provide a cost-effective, low-noise and high performance power solution. It has a wide voltage range (3.3V – 20V) and an output current up to 25A depending on temperature and other factors. It also has a wide input voltage range (2.5V to 6V).

This DC/DC switching controller can be used in a variety of applications:

• Industrial motor control
• Automotive electronics
• Telecommunication equipment
• Consumer electronics
• Battery charging systems
• Server and data center power supplies
• Medical instrumentation

The S-8521B18MC-ATDT2U switching controller works by providing an adjustable current output to regulate an external DC/DC converter. This is done by using a Pulse Width Modulation (PWM) technique that adjusts the duty cycle of a regulated waveform. The duty cycle is regulated by comparing a feedback voltage to the reference voltage, then adjusting the pulse width accordingly. This ensures a stable output current across a range of frequencies and input voltages. The S-8521B18MC-ATDT2U has a wide switching frequency range (300KHz to 1MHz) and can use multiple control methods including: resistor programing, on-chip adjustement, gain programming and internal/external synchronization.

The S-8521B18MC-ATDT2U switching controller also has an on-board temperature sensor in order to reduce peak power and thermal dissipation. The integrated overtemperature protection (OTP) also helps to protect the device from over-current and over-voltage conditions. Furthermore, it has a built-in UVLO (Under Voltage Lock Out) function which ensures safe and reliable operation. Soft start is also supported, providing a smooth transition from light to full load conditions.

The S-8521B18MC-ATDT2U switching controller supports a wide range of over-current and over-voltage protection features such as adjustable peak current limit and over-voltage protection. It also features a human-machine interface (HMI) for a user-friendly, intuitive experience. The HMI improves the control of the system by allowing the user to control and adjust settings such as: output voltage, current limit, and operating frequency.

The S-8521B18MC-ATDT2U is an ideal choice for system designers looking to provide cost-effective, low-noise and high performance power solutions. This switching controller can be used in a variety of applications, including: industrial motor control, automotive electronics, telecommunications equipment, consumer electronics, battery charging systems, server and data center power supplies, and medical instrumentation.
