The MCP1602-180I/MF from Microchip Technology is a fully integrated 500 mA synchronous buck regulator designed for high efficiency and compact solutions.
This device operates with a fixed 2.0 MHz PWM frequency under heavy loads, offering low noise and low output ripple. It automatically transitions to PFM mode at light loads to minimize quiescent current draw, achieving over 90% typical efficiency across a wide operating range. Key electrical features include a 2.7V to 5.5V input voltage range, 500mA output current, and a fixed 1.8V output voltage. Protection features include undervoltage lockout (UVLO), overtemperature protection, and overcurrent protection.
The MCP1602-180I/MF is available in an 8-lead DFN package, specifically an 8-DFN (3x3) with an exposed pad, suitable for surface mounting. Its low quiescent current of 45 µA (typical) and low shutdown current of 0.05 µA (typical) make it ideal for battery-powered applications.
Applications include cellular telephones, portable computers, organizers/PDAs, USB powered devices, digital cameras, portable equipment, and distributed systems requiring +5V or +3.3V.
