TPS61085T 具有强制 PWM 模式的 18.5V、2A、650kHz、1.2MHz 升压 DC-DC 转换器（扩展温度范围）
TPS61085T 描述
The TPS61085 is a high-frequency high-efficiency dc-to-dc converter with an integrated 2.0-A 0.13-Ω power switch capable of providing an output voltage up to 18.5 V. The selectable frequency of 650 kHz and 1.2 MHz 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 startup
