General Description
TS2515 consists of step-down switching regulator with PWM control. These devise include a reference voltage
source, oscillation circuit, error amplifier, internal PMOS and etc. TS2515 provides low-ripple power, high efficiency,
and excellent transient characteristics. The PWM control circuit is able to the duty ratio linearly form 0 up to 100%. 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-8L package, providing such outstanding features as low current
consumption. Since this converter can accommodate an input voltage up to 23V, it is also suitable for the operation
via an AC adapter.
