TinyBuck® DC-DC Regulator Family

onsemi's next-generation TinyBuck DC-DC regulator family provides higher system efficiency to help system designers meet tough energy standards and improve battery life while reducing total cost of ownership. The TinyBuck regulator family enables end-user applications to achieve greater than ninety-six percent efficiency over a very-wide load range.

This is achieved through multiple optimizations:
• Fine-tuned gate driver circuitry with optimized gate drive current and dead times for each specific
part number, giving two percent higher efficiency when compared to competitive solutions
• Constant on-time architecture with pulse frequency modulation (PFM) for highest light-load efficiency

Additional optimizations help improve thermal performance and system robustness:
• Reduced switch node ringing and optimized wide duty cycle achieved by leveraging our PowerTrench® MOSFETs with shielded gate technology
• Advanced packaging technology to minimize parasitic inductance and resistance to achieve superior thermal performance
