AH8665一般的描述
AH8665是一種高性能的開關(guān)模式電源電源控制器用于低功率離線應(yīng)用在典型降壓解決方案中具有最小的組件。集成電路內(nèi)置高擊穿電壓MOSFET承受高浪涌輸入。不像傳統(tǒng)的PWM控制，沒(méi)有固定的AH8665家族內(nèi)部時(shí)鐘觸發(fā)GATE驅(qū)動(dòng)器，開關(guān)頻率改變根據(jù)負(fù)載情況。多模式集成PWM控制，簡(jiǎn)化電路設(shè)計(jì)并達(dá)到良好的線路無(wú)負(fù)荷調(diào)節(jié)產(chǎn)生的音頻噪聲。峰值電流極限根據(jù)實(shí)際負(fù)荷情況進(jìn)行變化空載時(shí)待機(jī)功率低。AH8665集功能和保護(hù)于一體欠壓鎖(UVLO)，每周期限流(OCP)，輸出OVP，片上熱關(guān)機(jī)，過(guò)負(fù)荷保護(hù)(OLP)，VDD OVP與自動(dòng)恢復(fù)模式保護(hù)，等。
GENERAL DESCRIPTION
with minimum components in typical buck solution.The IC has built-in high break down voltage MOSFET to withstand high surge b.Unlike conventional PWM control, there’s no fixedinternal clock in AH8665 family to trigger the GATE driver, the switching frequency is changed according to the load condition. The multi mode PWM control is integrated to simplify circuit design and achieve good line and load regulation without audio noise generated. The peak current limit changes according to the real load condition for low standby power in no load.AH8665 integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Output OVP, On-chipThermal Shutdown, Over Load Protection (OLP), VDD OVP with Auto Recovery Mode Protection,
etc.
