FX5545G402 General Description
The DC/DC converter provides fully integrated synchronous boost converter solution for the latest one-cell lithium ion cellular phones. Its input voltage is between 2.5V to 6V, capable of delivering 1000mA of output current at 3.3V to 6V.
The DC/DC converter combines the 2MHz-switching controller with fully integrated passive components needed to deliver the smallest and most efficient converter available today. The high switching frequency minimizes the output capacitance with peak to peak output ripple as low as 20mV. The DC/DC converter delivers efficiency up to 95%.
The programmable pulse-skipping mode (PSM) maintains this high efficiency even during the standby and idle modes to increase overall battery life and talktime. In order to extract the last ounce of power from the battery, the DC/DC converter is designed with 100% duty cycle control for this mode. This function enables the DC/DC converter to operate like a saturated linear regulator delivering the highest potential output voltage for longer talk time.
The DC/DC converter is available in 20-ports BGA package. In order to satisfy the stringent ambient temperature requirements, the DC/DC converter is designed to handle the industrial temperature range of - 40°C to + 85°C.
