Description
General part information
MCP1602 Series
The MCP1602 is a high efficient, fully integrated 500 mA synchronous buck regulator with a power-good monitor. The 2.7V to 5.5V input voltage range and low quiescent current (45 µA, typical) makes the MCP1602 ideally suited for applications powered from 1-cell Li-Ion or 2-cell/3-cell NiMH/NiCd batteries.
At heavy loads, the MCP1602 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 MCP1602 automatically changes operation to a PFM mode to minimize quiescent current draw form the battery. No intervention is necessary for a smooth transition from one mode to another. These two modes of operation allow the MCP1602 to achieve the highest efficiency over the entire operating current range.
The open-drain power-good feature of the MCP1602 monitors the output voltage and provides indication when the output voltage is within 94% (typical) of the regulation value. The typical 2% hysteresis in the power-good transition threshold as well as a 262 ms (typical) delay time ensures accurate power good signaling.
