1 TC96C55 3A OUTPUT PROGRAMMABLE POWER OSCILLATOR FEATURES s s s s s Controllable Duty Cycle Wide Operating Range ............................. 5V to 18V High Peak Output Current .................................. 3A High Capacitive Load Drive Capability .................................... 1800pF in 20nsec Short Delay Time ............................. < 150nsec Typ GENERAL DESCRIPTION The TC96C555 Power Oscillator is an easily programmed IC that can be used in simple switch-mode power supplies, diode doublers and inverters, and similar circuits where high-current pulses are needed in an economical form. The TC96C555 uses TelCom Semiconductors' new Tough CMOS™ process. The output drive capability is similar to the TC4423/4/5 MOSFET Drivers, which can switch in 25nsec into a capacitive load of 1,800pF. The TC96C555 will not latch up under any conditions within their power and voltage ratings. They can accept, without damage, up to 1.5A of reverse current (of either polarity) being forced back into the output. All terminals are also fully protected against up to 4kV of electrostatic discharge. The peak output is rated at 3A. Split outputs permits driving of an external pair of MOSFETS, with controllable cross conduction between upper and lower devices.
