Digital Power Factor Correction Control IC

Features & Description

Overview

 Digital EMI Noise Shaping

The CS1501 is a high-performance digital power factor

correction (PFC) controller designed for switching mode power

supply (SMPS) applications. The CS1501 actively manages

the power factor correction while achieving high efficiency over

a wide load range.

 Adaptive Digital Energy Controller

• Excellent Efficiency Under All Load and Line Conditions

• Zero-voltage Switching Topology

 Minimal External Devices Required

 Adaptive Digital Control Loop

The CS1501 adaptively controls the input AC current so that it

is in phase with the AC mains voltage and its waveform mimics

the input voltage waveform. The PFC controller executes

adaptive digital algorithms designed to shape the AC mains

input current waveform to be in phase with the input voltage

waveform.

 Comprehensive Safety Features

• Undervoltage Lockout (UVLO)

• Output Overvoltage Protection

• Cycle-by-cycle Current Limiting

• Open/Short Loop Protection for IAC & IFB Pins

• Thermal Shutdown

The CS1501 is equipped with a zero-current detection (ZCD)

circuit providing the PFC digital controller the capability to turn

on the MOSFET when the voltage across the drain and source

is near zero. Additionally, a current-sensing circuit is

incorporated for instantaneous overcurrent protection.

 Pin placement similar to traditional boundary mode (CRM)

Controllers
