SG6846WALSY
SG6846WALSY - Brand New Fairchild Semiconductor IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The highly integrated SG6846 series of PWM controllers provides several features to enhance the performance of flyback converters. To minimize standby-power consumption,a proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions. Under zero-load conditions, the power supply enters burst-mode. This completely shuts off PWM output.
Features
Low Startup Current: 8µA
Low Operating Current: 3.7mA
Peak-Current Mode of Operation with Cycle-by Cycle Current Limiting
PWM Frequency Continuously Decreasing with Burst Mode at Light Loads
VDDOver-Voltage Protection (OVP)
AC Input Brownout Protection with Hysteresis
Constant Output-Power Limit (Full AC Input Range)
Internal Latch Circuit for OVP, OTP, and OCP
Two-level Over-Current Protection (OCP) with 96ms Delay Time
Very Few External Components
Programmable Over-Temperature Protection (OTP)
Applications
General-purpose switch-mode power supplies and flyback power converters,
including:
Power Adapters
Open-Frame SMPS
SMPS with Surge-Current Output, such as for Printers, Scanners, Motor Drivers
