R1223N332F-TR-FE

Overview

The R1223N332F-TR-FE is a CMOS-based PWM/VFM step-down DC/DC controller manufactured by Nisshinbo Micro Devices. It operates with an input voltage range of 2.3 V to 13.2 V and features a switching frequency of 300 kHz. The device supports positive output configuration and utilizes an external power transistor for current handling. It is housed in a compact SOT-23-5 package, designed for efficient power management in space-constrained applications.

Feature Summary

Supports hybrid PWM/VFM control modes for optimized efficiency across varying load conditions
Requires external power transistor and passive components for circuit implementation
Operates within a wide input voltage range suitable for battery-powered systems

Applications

Battery-powered portable electronic devices
General-purpose step-down power supply circuits
Embedded systems requiring efficient voltage regulation

Procurement Notes

Verify the specific suffix 'F' against official datasheets to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with external component selection, particularly the power transistor and inductor values, as this is a controller rather than a complete regulator module. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when a dedicated switching controller is preferred over integrated regulators for higher current flexibility. Consider the need for external MOSFET selection and thermal management. Evaluate the 300 kHz frequency against EMI constraints and inductor size requirements compared to higher-frequency alternatives.

Part Context

This part belongs to the R1223N series of step-down DC/DC controllers. The series is characterized by its CMOS technology and ability to drive external transistors, offering designers flexibility in current rating and thermal performance beyond what fixed-integrated solutions provide.
