Industry Smallest and Lowest Profile Synchronous DC/DC
Buck Converter with High Output Density Power
FEATURES
• Fully integrated DC/DC converter
• High efficiency over large load range
• 2MHz switching frequency
• 100% duty cycle
• Power density - more than 80W/inch3
• 1uA shutdown current
• 2.7V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells)
• 1.5V to 3.6V output voltage with max output current of600mA
• Programmable PWM/PSM controls
• Low output ripple
• BGA/LGA construction
• Temperature range: - 40°C to + 85°C
• No external components needed
• Low profile
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 provides fully integrated synchronous
buck converter solution for the latest one-cell lithium ion cellu-
lar phones. Its input voltage is between 2.7V to 6V, capable of
delivering 600mA of output current at 1.5V to 3.6V.
The DC/DC converter is available in 20-ports BGA/LGA
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.
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%.
APPLICATION
• Cellular and cordless phones, PDAs and others
• Supply voltage source for low voltage chip sets
• Portable computers
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
• Battery back-up supplies
• Digital cameras
