The Renesas 7008S55PFI is a MOSFET controlled AC-DC converter IC. It is a Very High Frequency PWM type switching regulator IC that features high efficiency and stability. It is designed to provide a highly efficient, low-ripple, and low-cost power source from a wide range of AC line voltage sources. The IC includes an internal VCC regulator, an oscillator, an error amplifier, and a voltage-controlled oscillator (VCO). It also contains an LDO (Low Drop Out) regulator, a current protection circuit, and a low ripple output filter. The 7008S55PFI is suitable for applications such as external power supplies, computers, batteries, power management, LED lighting and much more.
