GENERAL DESCRIPTION
The XRP6142 is a synchronous step down
switching controller for over 15 Amps point-of-
loads converters and optimized to generate
and support DDR I, II and III memory
voltages requirements.
Optimized to operate from standard 3.3V and
5V rails, the XRP6142 supports conversions
down to 0.5V from an input voltage as low as
1V and can reach efficiencies of up to 96%.
Based on a constant on-time control scheme
and
operating
at
a
constant
switching
frequency over the whole input voltage range,
it provides excellent load transient response
while requiring no external compensation
components. Three selectable on-time options
allow for further switching frequency, solution
footprint and efficiency optimization.
Dedicated support for DDR I, II and II
memories is also provided. The XRP6142
easily generates VDDQ (VDD) or VTT voltages
while an on board buffer provides the buffered
VTT reference voltage.
Under-voltage Lock out, short-circuit and
over-current and over-temperature protection
insure
safe
operations
under
abnormal
operating conditions.
The XRP6142 is available in a compact RoHS
compliant “green”/halogen free 16-pin QFN
package.
