SG6846ALSZ規(guī)格書詳情

Description

The SG6846A is especially designed for SMPS with surge-current output, incorporated with a two-level OCP function. Besides the cycle-by-cycle current limiting, if the switching current is higher than two thirds the peak

current threshold for 1700ms, over-current protection is activated such that the SG6846A is latched off.

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 OCP Delay: 1600ms

Output Short-Circuited Delay Time: 100ms

Programmable PWM Frequency with Frequency Hopping

OCP Threshold is Half Peak Current Limit

Feedback Open-loop Protection with 1700ms Delay

Built-in Soft-Start

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
