The wide range VCC input capability enables the device to be biased from the secondary side output voltage rail, resulting in closed loop soft start. The UC3965 includes an accessible 2.5V precision reference which offers 0.4% initial and 1% reference accuracy over line, load, and full tempera- ture range with a low offset error amplifier, a 2X inverting amplifier/buffer, and an undervoltage lockout circuit. The IC is ideally suited for applica- tions where high precision PWM power supply regulation is required. Typically, the error amplifier is configured to compare a fraction of the to be regulated power supply voltage to the on-chip 2.5V reference. The 2X amplifier/buffer output is then used to drive a PWM controller or regulator. The UC3965 is also capable of driving an optocoupler diode for isolated applications. application INFO available |
