LT3476 的典型應用是一款四路輸出 DC-DC轉換器,設計用作驅動高電流 LED 的恒流源。固定頻率、電流模式架構可在較寬的電源和輸出電壓范圍內穩定運行。頻率調節引腳允許用戶在 200kHz 至 2MHz 之間編程開關頻率,以優化效率和外部組件尺寸
說明
Typical Application for LT3476 is a quad output DC-DC converter designed to operate as a constant-current source for driving high current LEDs. A fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages. A frequency adjust pin allows the user to program switching frequency between 200kHz and 2MHz to optimize efficiency and external component size
