BD9E201FP4-ZTL

Overview

The BD9E201FP4-ZTL is a single synchronous buck DC/DC converter from ROHM Semiconductor, featuring an integrated low on-resistance power MOSFET. It operates with an input voltage range of 4.5 V to 28 V and delivers an output current of 2 A. The device supports adjustable output voltages starting from 0.7 V. It utilizes current mode control architecture and functions at a switching frequency of 350 kHz. The component is housed in a compact TSOT-23-6L package.

Feature Summary

Integrates low on-resistance power MOSFETs for efficient synchronous buck conversion
Employs current mode control architecture for stable regulation
Supports adjustable output voltage settings beginning at 0.7 V

Applications

Portable electronic devices requiring efficient step-down power management
Battery-powered systems utilizing the 4.5 V to 28 V input range
Embedded applications needing compact synchronous buck regulation

Procurement Notes

Verify the specific suffix ZTL against official ROHM documentation to confirm pinout and thermal characteristics. Ensure compatibility with the BD9E201FP4-EVK-001 evaluation kit if development support is required. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a 2 A synchronous buck solution is required within a TSOT-23-6L footprint. It is suitable for designs operating between 4.5 V and 28 V input. Consider the 350 kHz switching frequency for inductor size trade-offs. Verify that the minimum 0.7 V output requirement aligns with load specifications.
