BD83070GWL-E2

Overview

The BD83070GWL-E2 is a synchronous buck-boost DC/DC converter IC designed for battery-powered devices. It features an input voltage range of 2V to 5.5V and provides a fixed output of 2.5V to 3.3V with a maximum output current of 1A. The device operates at a switching frequency up to 1.65MHz and achieves a peak efficiency of 97% at 200mA load. Its quiescent current is extremely low at 2.8µA. The component is housed in a UCSP50L1C package measuring 1.2x1.6mm, suitable for space-constrained applications.

Feature Summary

Integrated synchronous buck-boost topology with built-in low-loss MOSFETs
Ultra-low static current consumption for extended battery life
High power conversion efficiency across wide load ranges
Seamless transition between step-up and step-down modes

Applications

Wearable electronic devices
Internet of Things (IoT) sensors
Portable medical equipment such as electric toothbrushes
Personal care appliances like shavers

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the UCSP50L1C package dimensions align with the PCB footprint design. Confirm that the application does not require automotive-grade qualification, as this standard product is not recommended for vehicle use.

Selection Notes

Select this IC when designing compact battery-operated systems requiring both step-up and step-down capabilities from a single cell. It is optimal for applications prioritizing minimal standby current and high efficiency under varying load conditions. Consider the 1.65MHz switching frequency for passive component size reduction compared to lower-frequency alternatives.

Part Context

This component belongs to ROHM's series of ultra-low power switching regulators aimed at extending battery life in portable electronics. It complements other products in the lineup by offering a complete buck-boost solution within a miniature WLCSP package, addressing the industry demand for smaller form factors without sacrificing power performance.

Replacement Considerations

Check for BD83070GWL variants with different suffixes for packaging or temperature grade differences. Evaluate BD83850GWL if dual-channel boost/inverting functionality is required instead of a single buck-boost channel.

FAQ

Does the BD83070GWL-E2 support independent channel control?

No, it is a single-channel synchronous buck-boost converter. Independent channel control is a feature found in multi-channel models like the BD8316GWL.
