SCT2A26STER

Voltage Regulators - DC DC Switching Regulators Overview

The SCT2A26STER is a synchronous step-down DC-DC converter manufactured by SCT. It supports an input voltage range from 5.5V to 100V and delivers a continuous output current of 2A. The device features an upper switch with an on-resistance of 500mΩ. It operates at a fixed switching frequency of 300kHz and maintains a feedback voltage of 1.2V. Quiescent current is specified at 140µA, and it employs Pulse Frequency Modulation (PFM) for light-load efficiency. The component is housed in an ESOP-8L package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific ordering suffix against official SCT documentation to confirm pinout compatibility and thermal pad requirements. Ensure the selected variant matches the required ESOP-8L package dimensions. Cross-reference the datasheet for absolute maximum ratings to prevent overvoltage damage during system integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a wide input voltage range up to 100V is required alongside a 2A output capability. The integrated synchronous design reduces external component count compared to asynchronous alternatives. Consider the 300kHz switching frequency for balancing transient response and EMI performance in compact designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the SCT2A series of high-voltage synchronous buck converters. The series is designed for applications demanding robust performance across varying load conditions. The ESOP-8L package provides a balance between thermal dissipation and board space efficiency for medium-power applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes must match the 100V input rating, 2A output current, and ESOP-8L package. Verify that alternative controllers support similar PFM operation and 300kHz switching frequencies to maintain circuit stability.
