MCP1602
2.0 MHz, 500 mA Synchronous Buck Regulator
with Power-Good
Features General Description The MCP1602 is a high efficient, fully integrated
500 mA synchronous buck regulator with a powergood monitor. The 2.7V to 5.5V input voltage range and
low quiescent current (45 ВµA, typical) makes the
MCP1602 ideally suited for applications powered from
1-cell Li-Ion or 2-cell/3-cell NiMH/NiCd batteries. Over 90% Typical Efficiency
Output Current: Up To 500 mA
Power-Good Output with 262 ms Delay
Low Quiescent Current: 45 ВµA (typical)
Low Shutdown Current: 0.05 ВµA (typical)
Automatic PWM to PFM Mode Transition
Adjustable Output Voltage:
-0.8V to 4.5V
Fixed Output Voltage:
-1.2V, 1.5V, 1.8V, 2.5V, and 3.3V
