  • Product Introduction

A8580 专为满足新一代车载音响和车用资讯娱乐系统的供电需求而设计,它可提供运行一个输出电压精准度为 ±1.0% 的大电流稳压器所需的所有控制和保护电路。通过利用脉冲宽度调制 (PFM),A8580 可在 12 V input voltage下仅耗用不足 50 μA 的电流并供应 3.3 V/40 μA 的电量。启动后,A8580 可至少 3.6 V input voltage下运行(输入voltage下降)。

A8580 的功能包括用以启用 PWM(逻辑高)或 PFM(逻辑低)的 PWM/PFMn 模式控制输入。若 PWM/PFMn 输入由高于基础频率的外部时钟信号驱动 (fOSC),PWM 频率将与输入时钟频率同步。SLEEPn 输入引脚控制极低的电流关机模式,在 16 V input voltage和 85ºC 的温度下,该模式需要为内部电路提供至少 5 μA 的电流,为 MOSFET 泄漏提供 10 μA(最大)的电流。A8580 利用外部补偿兼容各种频率和外部元件,并提供经输出电压验证的上电复位 (NPOR) 信号。

The A8580's extensive protection features include pulse-by-pulse current limiting, burp mode short-circuit protection, open/short-circuit asynchronous diode protection, BOOT open/short-circuit voltage protection, VIN undervoltage lockout, VOUT overvoltage protection, and overtemperature shutdown.

The A8580 is available in an ultra-thin 16-pin TSSOP package with an exposed power strip (suffix LP). The package is a lead-free (Pb) package with 100% matte tin plating on the pin frame.
