MCP1603 Synchronous Buck Regulator
The MCP1603 is a highly 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 protection features
include: UVLO, overtemperature and overcurrent protection.
