TPS61085DGKR – Boost Switching Regulator IC 2A VSSOP-8

The TPS61085DGKR from Texas Instruments is a high-frequency, high-efficiency DC-DC boost converter designed to deliver stable and efficient power for a wide range of portable and industrial applications. Operating from a 2.3V to 6V input voltage range, it is capable of generating output voltages up to 18.5V, making it ideal for LED backlighting, LCD bias supplies, and other voltage step-up applications. This device integrates a 2A, 0.13Ω power switch, providing excellent efficiency and strong current capability in a compact design. The selectable switching frequency of 650kHz or 1.2MHz enables designers to balance between efficiency and size—allowing the use of smaller inductors and capacitors while maintaining fast transient response. The TPS61085 features external loop compensation, giving flexibility to optimize performance for specific load and system requirements. A soft-start function, controlled by an external capacitor, ensures smooth startup and limits inrush current. The device includes comprehensive protection features such as thermal shutdown and undervoltage lockout (UVLO), ensuring reliable operation even under challenging conditions.

Key Features:

  • Wide Input Voltage Range: 2.3V to 6V suitable for single Li-Ion or multi-cell battery systems.
  • High Output Voltage: Up to 18.5V boost capability.
  • Integrated Power Switch: 2A, 0.13Ω low-RDS(on) switch for high efficiency.
  • Selectable Frequency: 650kHz or 1.2MHz for design flexibility and compact filtering.
  • External Compensation: Optimizes stability and transient performance.
  • Adjustable Soft-Start: Limits inrush current during power-up.
  • Comprehensive Protections: Thermal shutdown and undervoltage lockout (UVLO).
  • Compact 8-Pin VSSOP Package: Ideal for high-density PCB layouts.
  • Applications: LCD bias supplies, LED drivers, portable instrumentation, battery-powered equipment, and industrial electronics.
