Overview
The BD91390MUV-E2 is a switching voltage regulator manufactured by ROHM Semiconductor, classified under PMIC - Power Management ICs. It functions as a synchronous buck converter designed for step-down applications. The component utilizes the VQFNV4040-EP-20 surface-mount package and supports SMD/SMT installation styles. It operates within an input voltage range of 2.7 V to 5.5 V and provides a single output channel with adjustable voltage from 800 mV to 3.3 V. The device delivers a maximum output current of 4 A with a typical static current of 10 uA and a switching frequency of 1 MHz. It features a shutdown function and operates across a temperature range of -40 C to +105 C.
Feature Summary
- Integrates power MOSFETs for efficient synchronous buck conversion
- Supports wide input voltage ranges suitable for various power sources
- Includes shutdown functionality for power management control
Applications
- Portable electronic devices requiring efficient power regulation
- Embedded systems utilizing single-output DC-DC conversion
- Industrial equipment operating within specified temperature ranges
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check end-of-life notifications, as this part may be marked NRND (Not Recommended for New Designs). Ensure packaging specifications match project requirements, including reel or cut tape options. Validate technical parameters against the latest datasheet before integration.
Selection Notes
Evaluate thermal performance and heat dissipation capabilities given the 4 A output capability in a compact package. Consider the 1 MHz switching frequency for EMI constraints and passive component sizing. Assess compatibility with system input voltages ranging from 2.7 V to 5.5 V. Review shutdown current requirements if low-power standby modes are critical. Compare against alternative models in the BD913xx series for specific feature needs.
Part Context
This component belongs to the BD91361MUV series family, sharing similar architectural characteristics and package types. It serves as a high-current synchronous buck converter option within ROHM's PMIC portfolio. The part is distinct from lower-current variants like the BD9141MUV-E2 and multi-output models such as the BD9151MUV-E2. Its design focuses on balancing efficiency, size, and output current capacity for demanding applications.
Replacement Considerations
The BD91361MUV-E2 is listed as a recommended alternative. Verify pinout compatibility and parameter alignment before substitution. Note that the BD91390MUV-E2 may have different availability status compared to active replacements.
