RS2051 Overview
Description
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 Burst/CRM (Cycle Reset Mode) under light-load/zero-load conditions.
Key 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
- Audio Noise Free Operation
- Soft Clamped GATE output voltage 18V
- VDD over voltage protect 34V
