闽台致新G5699双通道高效单片同步降压调节器

      The G5699 is a dual channel high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 50μA and drops to <1μA in
shutdown for each channel. The 2.7V to 5.5V input voltage range makes the G5699 ideally suited for single
Li-Ion battery-powered applications. Both regulators have independent input and enable pins. **
duty cycle provides low dropout operation, extending battery run time in portable systems. Switching frequency is internally set at 1.4MHz, allowing the use of small surface mount inductors and capacitors. The
internal synchronous switch increase efficiency and eliminates the need for an external Schottky diode.
Built-in soft start function eliminates in-rush current that could damage the system. The G5699 is available
in TDFN3X3-12 package.
