The MCP1603LT-150I/OS from Microchip Technology is a fully integrated 500 mA synchronous buck regulator designed for applications powered by 1-cell Li-Ion or 2-cell/3-cell NiMH/NiCd batteries, with an input voltage range of 2.7V to 5.5V.
This device operates at a fixed 2.0 MHz PWM frequency under heavy loads, offering a low noise and low output ripple solution. For light loads, the MCP1603/L variants automatically transition to Pulse Frequency Modulation (PFM) mode to minimize quiescent current draw, achieving high efficiency across the entire operating current range. The MCP1603B variant operates exclusively in PWM mode.
Key features include over 90% typical efficiency, low shutdown current of 0.1 µA typical, and Undervoltage Lockout (UVLO) and overtemperature protection. The MCP1603LT-150I/OS is available in a space-saving, 5-lead TSOT-23-5 package, making it suitable for portable equipment and other space-constrained applications.
Applications include cellular telephones, portable computers, organizers/PDAs, USB powered devices, digital cameras, and +5V or +3.3V distributed systems.
