AX3106
PWM Control 2A Step-Down Converter
GENERAL DESCRIPTION
AX3106 consists of step-down switching regulator with PWM control. These devise
include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and
etc.
AX3106 provides low-ripple power, high efficiency, and excellent transient
characteristics. The PWM control circuit is able to every 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-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.
FEATURES
- Input voltage3.6V to 23V
- Output voltage0.8V to VCC
- Duty ratio0% to 100% PWM control
- Oscillation frequency330KHz typ.
- Soft-start (SS), Current Limit (CL), Enable function.
- Thermal Shutdown function.
- Short Circuit Protect (SCP).
- Built-in internal SW P-channel MOS.
- Low ESR output capacitor (Multi-layer chip capacitor (MLCC)) application.
- SOP-8L Pb-Free package.
