CR6853T datasheet pdf

Description

CR6853T is a highly integrated, low-cost, current-mode PWM controller designed for low-power offline AC-DC flyback converters and switching power supplies. Built-in synchronized slope compensation enhances the stability of the system and avoids sub-harmonic oscillation. Dynamic peak current limiting circuit minimizes output power change caused by delay time of the system over a universal AC input range. Leading edge blanking circuit on current sense input could remove the signal glitch due to snubber circuit diode reverse recovery and thus greatly reduces the external component count and system cost in the design. Cycle-by-Cycle current limiting ensures safe operation even during short-circuit.

It combines PWM, PFM, and Cycle Reset Mode (CRM) operation with programmable switching frequency, synchronized slope compensation, low-EMI control, approximately 1.5µA startup current, and comprehensive protection functions to improve efficiency and system reliability under different load conditions. Typical applications include AC-DC adapters, battery chargers, open-frame switching power supplies, standby power supplies, set-top box power supplies, and replacement designs based on the 384X PWM controller family.

Features

  • Highly integrated, low-cost current-mode PWM controller
  • Combined PWM, PFM, and Cycle Reset Mode (CRM) operation
  • Low startup current of approximately 1.5µA
  • Low operating current of approximately 1.4mA
  • Programmable switching frequency using external resistors
  • Automatic transition to PFM/CRM operation under light-load and zero-load conditions
  • Current-mode control for stable output regulation
  • Built-in synchronized slope compensation to improve system stability and prevent subharmonic oscillation
  • Integrated low-EMI technique and soft gate driver
  • Leading-edge blanking (LEB) on the current-sense input
  • Dynamic peak current limiting for consistent output power across a universal AC input range
  • Constant output power limiting
  • Soft-clamped gate output voltage with a maximum clamp level of 18.0V
  • Latch-mode protection following OLP and SCP events
  • High-voltage CMOS process with ESD protection

Description

MP3401A is a power bank solution device which is highly integrated with linear charger, LED battery display cell and synchronous boost output. The MP3401A has two operating modes, charge mode and boost mode, to manage the system and battery power based on the state of the input. When input power is present, the MP3401A operates in charge mode. It automatically detects the battery voltage and charges the battery in the three phases: trickle current mode, constant current mode and constant voltage mode. In the absence of input source, MP3401A switches to boost mode automatically when the battery voltage is higher than 3.2V.
