General 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.

This can minimize standby power consumption and achieve power-saving functions.

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.
  • Cycle-by-cycle current limiting.
  • Sense Fault Protect ion.
  • Latch mode Aft.
