TPS61085SLVS859B –JUNE 2008–REVISED DECEMBER 2014
TPS61085 650-kHz,1.2-MHz, 18.5-V Step-Up DC-DC Converter Features 3 DescriptionThe TPS61085isa high frequency, high efficiency 2.3Vto6V Input Voltage Range DC-DC converter with an integrated 2.0-A, 0.13-Ω• 18.5-V Boost Converter With 2.0-A Switch Current power switch capableof providing an output voltage• 650-kHz/1.2-MHz Selectable Switching Frequency upto 18.5V. The selectable frequencyof 650 kHzor
1.2 MHz allows the useof small external inductors• Adjustable Soft-Start and capacitors and provides fast transient response.• Thermal Shutdown The external compensation allows optimizing the• Undervoltage Lockout application for specific conditions. A capacitor
connected to the soft-start pin minimizes inrush• 8-Pin VSSOP Package
