TEXAS INSTRUMENTS UC3845AD8TR 控制器, 电流模式控制器, PWM, 30V-7.6V电源, 500 kHz, 15V/200mA输出, SOIC-8
The is a current-mode Pulse Width Modulation PWM Controller providing the necessary features to control current-mode switched mode power supplies. Start-up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA. During under voltage lockout, the output stage can sink at least 10mA at less than 1.2V for VCC over 5V.
