产品名称:RY8001 5.5V 1A 1.5MHz 同步降压稳压器
型号: RY8001
产片介绍:The RY8001 is a high-efficiency monolithic synchronous buck regulator using a constant frequency

┄┄┄详细介绍┄┄┄

1.General Description
The RY8001 is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode
architecture. The device is available in fixed 1.25V output voltage. Supply current drops to 0.1uA in shutdown
mode. The 2.5V to 5.5V input voltage range makes the RY8001 ideally suited for single Li-Ion battery powered
applications. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications.
Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors.
The RY8001 requires a minimal number of readily available, external components and is available in a space saving
SOT23-5 and SON763 package
