Overview
The BU24024GU-E2 is a DC-DC converter IC designed for step-up voltage conversion. It operates with an input voltage range of 0.9V to 5.5V and provides a fixed output voltage of 3.3V or 5V, selectable via external pins. The device integrates a power MOSFET capable of delivering up to 1A peak current. It features a switching frequency of approximately 1.2MHz, allowing for the use of small inductors and capacitors. The IC includes protection functions such as over-current protection and thermal shutdown to ensure reliable operation under various load conditions.
Feature Summary
- Integrated high-efficiency step-up DC-DC converter topology
- Built-in power MOSFET for compact circuit design
- Multiple safety protections including over-current and thermal shutdown
Applications
- Portable battery-powered devices requiring voltage boosting
- Mobile phones and smartphones for peripheral power supply
- Digital cameras and camcorders using single-cell lithium batteries
Procurement Notes
Verify the specific suffix 'E2' indicates lead-free compliance and RoHS directive adherence. Confirm the package type matches the required PCB footprint. Ensure the selected output voltage variant aligns with system requirements. Check for any regional distribution restrictions or obsolescence notices before finalizing procurement plans.
Selection Notes
Consider the input voltage range relative to the power source, such as single-cell lithium-ion batteries. Evaluate the required output current against the internal MOSFET capabilities. Assess the need for external components like inductors and capacitors based on efficiency targets. Verify compatibility with the target application's operating temperature range and space constraints.
Part Context
This component belongs to Rohm's series of step-up DC-DC converters aimed at portable electronics. It simplifies power management by integrating control logic and power switches. The family focuses on high efficiency and small form factors suitable for modern mobile devices. Other models in the series may offer different output voltages or current capacities.
Replacement Considerations
Direct substitutes should be checked for pin-to-pin compatibility and identical electrical specifications. Verify that alternative parts support the same input voltage range and output configuration. Ensure equivalent protection features are present to maintain system reliability. Consult manufacturer cross-reference lists for validated replacements.
