MAX17690为峰值电流模式、固定开关频率控制器，特别设计用于工作在非连续传导模式 (DCM)的隔离反激结构。 器件直接检测原边开关关断期间原边反激波形的隔离输出电压，无需辅助绕组或光耦调节输出电压。 MAX17690设计工作在4.5V至60V较宽电源范围。 开关频率从50kHz至250kHz可编程。 EN/UVLO引脚允许用户在相应输入电压时准确开启/关断电源。 MAX17690通过OVI引脚提供输入过压保护。 MAX17690的内部LDO输出为7V，使其非常适合切换逻辑电平 …

The MAX17690D evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the operation of an isolated 15W no-opto flyback DC-DC converter with secondary-side synchronous rectification. This circuit is implemented using the MAX17690, a no-opto, flyback controller in a 16-pin TQFN package with an exposed pad.

MAX17690ATE+ – Flyback Regulator Positive, Isolation Capable Output Step-Up/Step-Down DC-DC Controller IC 16-TQFN (3x3) from Analog Devices Inc./Maxim Integrated. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

The MAX17690 is a peak current mode, fixed-frequency switching controller specifically designed for the isolated flyback topology operating in Discontinuous Conduction Mode (DCM). The device senses the isolated output voltage directly from the primary-side flyback waveform during the off-time of the primary switch.

2016年9月15日 · The Analog Devices MAX17690 Isolated Flyback Controller has robust hiccup-protection and thermal protection schemes and is available in a space-saving 16-pin 3mm x 3mm TQFN package with a temperature range from -40°C to 125°C.

2007年10月10日 · ACDelco Professional, premium aftermarket V-Belts serve as replacement belts for today’s most demanding engine drives. Due to thermal forces, these variable notched belts actually tighten on the drive as they get hot. This results in improved belt performance by reducing tension, decay, and noise.

Fleetrite® belts are super tough and highly flexible. They're also abrasion-, oil- and chemical-resistant, which makes them a quality replacement solution for Original Equipment Manufacturer (OEM) and heavy-duty applications. Suitable for many makes and models of vehicles, Fleetrite belts will keep your vehicle running.
