G5691-33RB1U 电子元器件 GMT致新 封装TDFN2X2-6  1.5MHz, 1A高效降压转换器

General Description
The G5691 provides complete control for a DC/DC
converter optimized for high-performance microprocessor
applications. It is operated on current mode
architecture for excellent line and load transient response.
1.5MHz operation frequency is allowing the
use of small surface mount inductor and capacitor.
The internal synchronous switch increases efficiency
and eliminates the need for an external Schottky diode.
The G5691 is a family of low-noise synchronous
step-down DC/DC converters that is ideally suited for
systems powered from a 1-cell Li-ion battery or from a
3-cell to 4-cell NiCd, NiMH, or alkaline battery. It can
also be used to USB-Based power system.
