Part number: RS2051
Manufacturer: PTC
File Size: 541.85 KB
Datasheet: RS2051-PTC.pdf
Description: Green-Mode PWM Controller

Features

* Low Cost, PWM, Burst & CRM (Cycle Reset Mode)
* Low Operating Current (1.2mA)
* Low Start-up Current (about 3μA)
* Under Voltage Lockout (UVLO)
* Built-in Synchronized Slope Compensation
* Built-in Frequency Jiggling for better EMI Signature
* Programmable PWM Frequency

Applications

* Making use of external resistors, the IC changes the operating frequency and automatically enters the Burst/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 coul
