LM3204TL/NOPB-Miniature, Adjustable, Step-Down DC-DC Converter with Bypass Mode for RF Power Amplifiers

The LM3204 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell. It steps down an input voltage of 2.7V to 5.5V to an adjustable output voltage of 0.8V to 3.6V. The output voltage is set using an analog input ( VCON) for optimizing efficiency of the RF PA at various power levels.

The LM3204 offers superior features and performance for mobile phones and similar RF PA applications. Fixed-frequency PWM mode minimizes RF interference. Bypass mode turns on an internal bypass switch to power the PA directly from the battery. LM3204 has both forced and automatic bypass modes. Shutdown mode turns the device off and reduces battery consumption to 0.1µA (typ.).

The LM3204 is available in a 10-pin lead free DSBGA package. A high switching frequency (2MHz) allows use of tiny surface-mount components. Only three small external surface-mount components, an inductor and two ceramic capacitors are required.
