General Description

PR9853 is a highly integrated and low cost current mode PWM controller, which is ideal for low power current mode of offline AC-DC fly-back converter applications.

By adjusting the external resistors to change the operating frequency, and then IC automatically enters PFM or hiccup mode in light-load or zero-load condition.

Thereby reduce the standby power loss and achieve power-stored function.

Key Features

l Low Cost, PWM&PFM&hiccup mode l Low Start-up Current (about 3μA) l Low Operating Current (about 1.2mA) l Current Mode Operation l VDD Under Voltage Lockout (UVLO) l Built-in Synchronized Slope Compensation l Built-in Low EMI Technique l Programmable PWM Frequency l Audio Noise Free Operation l Leading edge Blanking on SEN input l Constant output power limiting in universal AC input Range l SOT-23-6L and DIP-8 Pb-Free Packaging l Good Protection Coverage With Auto Self-Recovery Complete Protec.
