TEXAS INSTRUMENTS UC3856NG4 控制器, 电流模式控制器, PWM, 40V-8V电源, 1 MHz, 13.1V/200mA输出, DIP-16
The is a high-performance current-mode Pulse Width Modulation PWM Controller intended for both design upgrades and new applications where speed and accuracy are important. All input to output delays have been minimized and the current sense output is slew rate limited to reduce noise sensitivity. Fast 1.5A peak output stages have been added to allow rapid switching of power FETs. A low impedance TTL compatible sync output has been implemented with a tri-state function when used as a sync input. This is in conjunction with the improved differential current sense amplifier results in enhanced noise immunity. Other features include a trimmed oscillator current 8% for accurate frequency and dead time control.
