Overview
The S-8520B30MC-ARPT2U is a step-down switching controller IC from the ABLIC S-8520 series. It operates with an input voltage range of 2.5V to 16V and provides a fixed output voltage of 3.0V. The device utilizes PWM control with a typical switching frequency of 300kHz. It features a low quiescent current of 100µA and includes an enable function for power management. Packaged in a compact SOT-23-5 format, it supports surface-mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrated step-down DC-DC switching controller topology
- Low quiescent current consumption for energy efficiency
- Built-in enable pin for system power control
- Compact SOT-23-5 surface-mount package
Applications
- Battery-powered portable electronic devices
- Embedded systems requiring stable 3.0V logic supply
- Industrial equipment with 2.5V to 16V input rails
- Consumer electronics utilizing step-down power regulation
Procurement Notes
Verify the exact suffix ARPT2U against official ABLIC documentation to confirm pinout and marking codes. Confirm RoHS compliance status via the manufacturer's latest environmental declaration. Check for end-of-life notices or obsolescence warnings before finalizing design-in decisions. Ensure supplier sources provide genuine components with traceable manufacturing dates.
Selection Notes
Select this component when a fixed 3.0V output is required from inputs up to 16V. The 300kHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the internal switch capabilities. Consider the SOT-23-5 footprint constraints during PCB layout planning.
Part Context
This part belongs to the S-8520 series of synchronous rectification switching regulators designed by ABLIC. The series focuses on high-efficiency power conversion in small packages. The S-8520B30 variant specifically targets applications needing a precise 3.0V output level. It complements other PMIC offerings for comprehensive power management solutions.
Replacement Considerations
Direct substitutes include other S-8520 series variants with compatible output voltages and pinouts. Cross-reference with similar ABLIC step-down controllers ensuring identical SOT-23-5 packaging. Verify electrical parameters match the original design requirements before substitution.
