“ MB39A135 (1-channel) ” and “ MB39A136 (2-channel) ” have been developed to
supply power voltage to image processing LSIs, microcontrollers, and so forth in digital
TVs, HDD recorders, and game machines.
Overview
Product Features
As markets for digital TVs and game machines are growing
increasingly active, the need for power-supply ICs to supply
power voltage to image processing LSIs, microcontrollers, and
so forth has been increasing. There are particularly strong
demands for high efficiency, high precision, excellent transient
response characteristics, and reduction in peripheral parts to

Current mode Nch/Nch synchronous rectification
Built-in PFM function
Input power-supply voltage range: 4.5V to 25V
Operating frequency: 100kHz to 1MHz
High-precision reference voltage: 0.7V ± 1 ％ (25 ℃ )
realize cost reduction.
To address these demands, this product offers high efficiency
operation in all load ranges through built-in PFM functions and
high speed transient load response characteristics that surpass
those of the conventional voltage mode by adopting the current
mode. Its substantial protective functions allow the elimination
of external protective elements. In addition, the miniaturization
of the coil and input and output capacitors through increasing
frequency, and the package size contributes to the reduction of
total PCB area including external parts. It also realizes power-
supply sequence control such as soft-start and soft-stop functions
that are required for use as a core supply or I/O supply for
systems.
