The MCP1603T-330I/OS from Microchip Technology is a fully-integrated 500mA synchronous buck regulator designed for efficient power conversion. It features a fixed output voltage of 3.3V and operates at a 2.0 MHz fixed-frequency PWM mode under heavy loads, providing a low noise and low-output ripple solution.
This regulator boasts over 90% typical efficiency and low quiescent current (45 µA typical in PFM mode) for battery-powered applications. It includes essential protection features such as undervoltage lockout (UVLO) and overtemperature protection. The device operates from an input voltage range of 2.7V to 5.5V.
Available in a compact TSOT-23-5 package, the MCP1603T-330I/OS is suitable for space-constrained designs. Its applications include portable equipment, cellular telephones, and USB-powered devices where efficient and reliable voltage regulation is critical.
Key electrical characteristics include a 500mA output current capability, a 2MHz switching frequency, and a 100% duty cycle operation. The device also offers a low shutdown current of 0.1 µA typical.
