Overview
The AP4313KTR-E1 is a constant voltage and constant current controller designed for switch-mode power supplies (SMPS). It operates within an input voltage range of 2.5 V to 18 V and draws a supply current of 600 µA. The device features an output current capability of 27 mA and functions reliably across a temperature range of -40 °C to +105 °C. Packaged in a compact SOT-23-6 surface-mount format, it integrates control logic for dual-loop regulation applications.
Feature Summary
- Integrates constant voltage and constant current control loops for SMPS applications
- Operates with low quiescent supply current for improved efficiency
- Supports wide input voltage ranges suitable for various power architectures
Applications
- Constant voltage/constant current mode switch-mode power supplies
- Battery charging systems requiring precise current limiting
- LED drivers with regulated output characteristics
Procurement Notes
Verify the specific suffix E1 against G1 variants to confirm exact manufacturing lot and compliance status. Confirm availability as this variant may be subject to discontinuation notices. Ensure the ordering code matches the required package and tape-and-reel specifications for your assembly line. Cross-reference the latest datasheet revision for any pinout or electrical parameter updates before finalizing procurement.
Selection Notes
Select this component when designing SMPS circuits that require integrated CV/CC control without external complex feedback networks. The SOT-23-6 package suits space-constrained designs. Verify that the 27 mA output drive capability meets the gate drive requirements of the external switching MOSFETs. Ensure the operating temperature range aligns with the thermal environment of the target application.
Part Context
This part belongs to the AP4313 series from Diodes Incorporated, specialized for power management ICs. It serves as a dedicated controller for dual-loop regulation, distinguishing itself from general-purpose op-amps by integrating specific protection and regulation features tailored for DC-DC conversion topologies.
Replacement Considerations
The AP4313KTR-G1 is a verified substitute within the same series. Check for EOL notifications regarding the E1 suffix. Ensure functional compatibility regarding pinout and electrical specifications before swapping.
