General Description
The MCP1603 is a high efficient, fully integrated
500 mA synchronous buck regulator whose 2.7V to
5.5V input voltage range makes it ideally suited for
applications powered from 1-cell Li-Ion or 2-cell/3-cell
NiMH/NiCd batteries.
At heavy loads, the MCP1603 operates in the 2.0 MHz
fixed frequency PWM mode which provides a low
noise, low output ripple, small-size solution. When the
load is reduced to light levels, the MCP1603
automatically changes operation to a PFM mode to
minimize quiescent current draw from the battery. No
intervention is necessary for a smooth transition from
one mode to another. These two modes of operation
allow the MCP1603 to achieve the highest efficiency
over the entire operating current range.
The MCP1603 is available with either an adjustable or
fixed output voltage. The available fixed output voltage
options are 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. When a
fixed option is used, only three additional small external
components are needed to form a complete solution.
Couple this with the low profile, small-foot print
packages and the entire system solution is achieved
with minimal size.
Additional
