Sanken’s Buck Regulator Outline
Sanken has the buck regulators such as high efficiency switching regulator and low noise linear regulator.
The PCB size can be reduced because the IC builds in the power transistors.
Sanken has the modules that the IC, the peripheral components and the Inductor are included.
Buck Switching Regulator
Non-synchronous
Switching Regulator
 Basic buck switching regulator .
 Simple control
 A freewheel diode is necessary (See P.83).
Synchronous
Switching Regulator




No required of freewheel diode
Space-saving
High-Efficiency
High frequency more than Non-synchronous
switching
Linear Regulator
LDO
DCDC-SGE
Feb.17,2016
 It is suitable for the use that switching noise can't be permitted.
 There are a few peripheral parts (Fixed output type).
 The difference in input and output is low (Low-drop out).

With Light-Load High Efficiency Function, Buck Switching Regulator Outline
Sanken’s buck switching regulators have high efficiency products in light load. The products has Lightload High Efficiency Function and achieves high efficiency of 85% max.
(without this function, η=40% to 50%)

NR119E
η=68%, Io=20mA
* Light-load High Efficiency Function, such
as the pulse skip mode and the burst
mode, reduce the circuit dissipation in
light load condition by decreasing
number of switching per unit time.
NR131A
η=85%, Io=10mA
NR131S
η=85%, Io=10mA
The measurement condition of efficiency, η is VIN=12V, Vo=5V.
