TPS61085DGKT

Импульсный повышающий DC-DC стабилизатор, регулируемый, 2.3В-6В (Vin), 2.8В-18.5В, 2А, MSOP-8.

The TPS61085DGKT is a 650kHz/1.2MHz Step-up DC-DC Converter with forced PWM mode and an integrated 2.0A, 0.13R power switch capable of providing an output voltage up to 18.5V. The selectable frequency of 650kHz or 1.2MHz allows the use of small external inductors and capacitors and provides fast transient response. The external compensation allows optimizing the application for specific conditions. A capacitor connected to the soft-start pin minimizes inrush current at start-up. This high frequency high efficiency boost converter's novel topology using adaptive off-time provides superior load and line transient responses and operates also over a wider range of applications than conventional converters. The converter operates in continuous conduction mode (CCM) as soon as the input current increases above half the ripple current in the inductor, for lower load currents it switches into discontinuous conduction mode (DCM).
