.DataSheet.co.kr AX3113 PWM Control 2A Step-Down Converter ™ GENERAL DESCRIPTION AX3113 consists of step-down switching regulator with PWM control. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc. AX3113 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%. 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 pensation block is built in to minimum external ponent 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 acmodate an input voltage up to 23V, it is also suitable for the operation via an AC adapter. ™ Features - Input voltage：4V to 23V - Output voltage：0.8V to Vcc - Duty ratio：0% to 100% PWM control - Oscillation frequency：330KHz typ. Current Limit(CL), Enable function. Thermal Shutdown function. Short Circuit Protect (SCP). Built-in internal SW P-channel MOS. SOP-8L Pb-Free package. NãtUFÿmñW3^VÛmw`R- yÑb€g- PQlSø .gofotech.
