Description: Novel Low Cost Green-Mode PWM Controller

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

Applications

* Making use of external resistors, the IC changes the operating frequency and automatically enters the PFM/CRM (Cycle Reset Mode) under light-load/zero-load conditions. This can minimize standby power consumption and achieve power-saving functions. With a very low start-up current, the RS2051 could
