The MIC2224YML-TR from Microchip Technology is a high-efficiency, 2MHz PWM synchronous buck switching regulator optimized for powering RF Power Amplifiers in 2.5G and 3G CDMA applications. It features a wide input voltage range of 2.7V to 5.5V, making it suitable for single-cell Li-Ion battery applications.
This regulator can deliver up to 600mA of output current in PWM mode and over 1A in bypass mode. The output voltage is dynamically adjustable down to 0.3V via an external DAC. A key feature is the internally protected 40mΩ bypass switch, which allows direct connection of the battery to the load when maximum power is required, maximizing PA efficiency.
The device operates with constant 2MHz PWM frequency, enabling the use of smaller external components and meeting stringent W-CDMA VOUT response specifications. It includes built-in power MOSFETs, internal soft-start, under-voltage lockout, and thermal shutdown and current limit protection. The MIC2224YML-TR is available in a 10-pin 3mm x 3mm MLF® package and operates within a junction temperature range of -40°C to +125°C.
It is ideal for applications such as cellular phones and PDAs requiring efficient power management for RF components.
