SG2846N

SG2846 系列 500 kHz 40 V 通孔 电流模式 PWM 控制器 - PDIP-16

DESCRIPTION

The SG1846 family of control ICs provides all of the necessary features to implement fixed frequency, current mode control schemes while maintaining a minimum external parts count. The superior performance of this technique can be measured in improved line regulation, enhanced load response characteristics, and a simpler, easier-to-design control loop.

FEATURES

• Automatic feed forward compensation

• Programmable pulse by pulse current limiting

• Automatic symmetry correction in push-pull configuration

• Enhanced load response characteristics

• Parallel operation capability for modular power systems
