【AX3131】
●AX3131 consists of step-down switching regulator with PWM control. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS andetc.
●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 with exposed pad 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.
▲Input voltage 4.5V to 23V
▲Output voltage VFB to VCC
▲Duty ratio 0% to 100% PWM control
▲Oscillation frequency 200K~1.3MHz (Outside resistance setting)
▲Current Limit (CL), Short Current Protection (SCP)
▲External Soft-Start function and Shutdown Function.
▲Thermal Shutdown function.
▲Built-in internal SW P-channel MOS.
▲SOP-8L with exposed pad Pb-Free package.
AX3131包括降壓開關穩(wěn)壓器的PWM控制。這些設計包括一個參考電壓源,振蕩電路,誤差放大器,內(nèi)部PMOS和等等。
AX3131提供低紋波電源,效率高,及出色的瞬態(tài)的特點。 PWM控制電路是能夠的占空比線性形成0至100%。
該轉換器的頻率可以設置由外部電阻。較寬的范圍是從200K到1.3MHz。 AX3131是打造出了軟啟動功能,防止浪涌電流和過沖。關斷開關,過電流保護和短路保護功能是建立在里面,SCP發(fā)生時,操作頻率將被降低至150K。此外,一個外部補償塊是建立在良好的穩(wěn)定系統(tǒng)。
◇4.5V至23V輸入電壓
