CR6850D Datasheet Novel Low Cost Green-power Pwm Controller

Manufacturer: Chip-Rail

Overview: CR6850D Novel Low Cost Green-Power PWM Controller.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The CR6850D 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 PFM/CRM (Cycle Reset Mode) under light-load/zero-load conditions.

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

Key Features

  • Low Cost, PWM&PFM&CRM (Cycle Reset Mode) Low Start-up Current (about 8µA) Low Operating Current (about 2mA) Current Mode Operation Under Voltage Lockout (UVLO) Built-in Synchronized Slope Compensation Programmable PWM Frequency Audio Noise Free Operation Leading edge Blanking on Sense input Constant output power limiting for universal AC input Cycle-by-cycle current limiting Soft clamped gate output voltage 16.8V Over voltage protect 25.5V High-Voltage CMOS Process with ESD SOT-23-6L、SOP-8 & DIP.
