General Description

TS19377 consists of step-down switching regulator with PWM control. These devise include a reference voltage

source, oscillation circuit, error amplifier, internal PMOS and etc.

TS19377 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control

circuit is able to the duty ratio linearly from 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-8 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.
