BD9B333GWZ-E2

Overview

The BD9B333GWZ-E2 is a single synchronous buck DC/DC converter manufactured by ROHM Semiconductor. It operates with an input voltage range of 2.7 V to 5.5 V and provides a regulated output voltage adjustable from 600 mV to 4.4 V. The device supports a maximum output current of 3 A and utilizes a fixed switching frequency of 1.3 MHz. Quiescent current is specified at 10 uA, while operating supply current is 50 uA. It functions within a temperature range of -40°C to +85°C and is housed in a UCSP35L1-16 surface-mount package.

Feature Summary

Integrates internal power MOSFETs for compact synchronous buck conversion
Employs constant on-time control architecture for rapid transient response
Features low quiescent current consumption for efficient standby operation

Applications

Portable electronic devices requiring high efficiency
Battery-powered systems needing low standby power
Embedded applications utilizing 3.3V or 5V input rails

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the UCSP35L1-16 package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the 3 A output capability under expected load conditions.

Selection Notes

Select this component when a single-output synchronous buck topology is required with integrated switches. It is suitable for designs prioritizing small form factor due to the UCSP package. Consider the 1.3 MHz frequency for balancing component size and efficiency. Verify input voltage stability remains within the 2.7 V to 5.5 V specification during all operational states.

Part Context

This part belongs to the BD9B33x series of integrated MOSFET DC-DC converters. These regulators are designed for applications demanding fast transient response and low light-load power consumption. The series utilizes constant on-time control to maintain stability across varying load conditions while minimizing external component count.
