With input voltages of 5V (-D5 models) and 12V (-D12 models) these converters  
offer standard output voltages of 1.8, 2.5 and 3.3 Volts and up to 10 Amps of output  
current in both through-hole and surface-mount 1" x 2" metal cases.  
With on/off control and output voltage trim capability as standard features, these  
non-isolated converters exploit full synchronous rectification, planar magnetics, and  
100% automated assembly to deliver high efficiencies (to 91%) and low noise at low  
cost.  
8 and 10 Amp output current models  
VOUT user-trimmable from 1.28V to 3.6V  
Non-isolated, full synchronous topology  
1" x 2" through-hole or SMT package  
Gull-wing leads for SMT package  
High efficiency to 91%; Low noise  
200kHz switching; Planar magnetics  
These versatile DC/DC’s are fully line and load regulated. They feature quick  
transient response (50µsec), user-optional on/off control (for power sequencing),  
and output overcurrent detection and shutdown ("hiccup" technique with auto-recov-  
ery). Their impressive guaranteed efficiencies enable them to deliver fully rated  
output power from –40 to +50/55°C (ambient) without supplemental cooling.  
If your high current requirements have made the use of inefficient linear regula-  
tors impractical, take a look at one of Murata Power Solutions’ new switching buck  
regulators. Their high efficiency, ease-of-use, long-term reliability, and overall cost  
effectiveness will impress you. Safety agency approvals and EMC characterizations  
are currently in progress.
