TS2508A
3A / 330KHz PWM Buck Converter
1/8
Version: A09
SOP-8
General Description
TS2508A consists of step-down switching regulator with PWM control. These devise include a reference voltage
source, oscillation circuit, error amplifier, internal PMOS and etc. TS2508A provides low-ripple power, high efficiency,
and excellent transient characteristics. The PWM control circuit is able to very the duty ratio linearly form 0 up to
100%. This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents overshoot at
startup. An enable function, an over current protect function and short circuit protect function are built inside, and
when OCP or SCP happens, the operation frequency will be reduced. Also, an internal compensation block is built in
to minimum external component count. With the addition of an internal P-channel Power MOS, a coil, capacitors, and
a diode connected externally, these ICs can function as step-down switching regulators. They serve as ideal power
supply units for portable devices when coupled with the SOP-8 package, providing such outstanding features as low
current consumption. Since this converter can accommodate an input voltage up to 20V, it is also suitable for the
operation via an AC adapter.
