Description: 650mA Step-Down DC-DC Converter

Features

* ! ! ! PWM Switching Frequency: 2MHz Single Lithium-Ion Cell Operation (2.7V to 5.5V) Dynamic Programmable Output Voltage (1.3V to 3.16V) Maximum load capability of 650mA High Efficiency (96% Typ at 3.6VIN, 3.16VOUT at 400mA) from internal synchronous rectification Current Overload Protection Therma

Applications

* The AS1332 steps down an input voltage of 2.7V to 5.5V to output voltages ranging from 1.3V to 3.16V. Using a VCON analog input, the output voltage is set for controlling power levels and efficiency of the RF PA. The RF interferences are minimized due to the fixedfrequency PWM operation. The batter
