Description: | 2.5MHz/1.5MHz Step-Down Converters with 60m ohm Bypass in TDFN for CDMA PA Power |
Manufacturer: | Maxim Integrated Products |
Datasheet: | PDF (263K). Click here to download *) |
The MAX8581/MAX8582 high-frequency step-down converters are optimized for dynamically powering the power amplifier (PA) in CDMA handsets. They integrate a highefficiency PWM step-down converter for medium- and low-power transmission and a 60m (typ) bypass mode to power the PA directly from the battery during highpower transmission. They use an analog input driven by an external DAC to control the output voltage linearly for continuous PA power adjustment. The MAX8581/ MAX8582 use an internal feedback network, and the switching frequency is internally set to 2.5MHz and 1.5MHz, respectively. |
