The implemented boost Output Power or Forced PWM converter is based on a fixed frequency of 1.2-MHz, pulse-width-modulation (PWM) controller that allows • Adjustable Soft-Start the use of small external inductors and capacitors • Thermal Shutdown and provides fast transient response. • Undervoltage Lockout At light-load, the device can operate in Power Save • 10-Pin VSON Package Mode with pulse-frequency-modulation (PFM) to improve the efficiency while keeping a low-output 2 Applications voltage ripple. For very noise-sensitive applications, the device can be forced to PWM Mode operation • Handheld Devices over the entire load range by pulling the MODE pin • GPS Receivers high. The external compensation allows optimizing • Digital Still Cameras the application for specific conditions. A capacitor • Portable Applications connected to the soft-start pin minimizes inrush current at start-up. • DSL Modems • PCMCIA Cards Device Information(1) • TFT LCD Bias Supply PART NUMBER PACKAGE BODY SIZE (NOM) TPS61086 VSON (10) 3.00 mm × 3.00 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
