RS2051 - Novel Low Cost Green-Mode PWM Controller
The RS2051 is a highly integrated low cost current mode PWM controller, which is ideal for small power current mode of offline AC-DC fly-back converter applications.
Making use of external resistors, the IC changes the operating frequency and automatically enters the PFM/CRM (Cycle Reset Mode) under
RS2051 Features
* Low Cost, PWM&PFM&CRM (Cycle Reset Mode) Low Start-up Current (about 1.5μA) Low Operating Current (about 2.2mA) Current Mode Operation Under Voltage Lockout (UVLO) Built-in Synchronized Slope Compensation Built-in fixed soft start with 1.2mS Built-in Frequency jitter for better EMI Signature Program
