LM1770
SOT-23 Synchronous Buck Controller
General Description
The LM1770 is an efficient synchronous buck switching con-
troller in a tiny SOT23 package. The constant on-time control
scheme provides a simple design free of compensation com-
ponents, allowing minimal component count and board
space. It also incorporates a unique input feed-forward to
maintain a constant frequency independent of the input volt-
age. The LM1770 is optimized for a low voltage input range
of 2.8V to 5.5V and can provide an adjustable output as low
as 0.8V. Driving an external high side PFET and low side
NFET it can provide efficiencies as high as 95%.
Three versions of the LM1770 are available depending on
the switching frequency desired for the application. Nominal
switching frequencies are in the range of 100kHz to
1000kHz.
