General Description
The TS2507 integrates Pulse-Width-Modulation (PWM) control circuit into a single chip. These devise include a
reference voltage source, oscillation circuit, error amplifier and etc. TS2507 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 controller 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 external P-channel Power MOS, a coil, capacitors, and
a diode connected externally, these components can function as step-down switching regulators. They serve as ideal
power supply units for portable devices when coupled with the SOP-8, providing such outstanding features as low
current consumption. Since this converter can accommodate an input
