ISL80020, ISL80020A, ISL80015, ISL80015A pact Synchronous Buck Converters FN6692 Rev 3.00 June 5, 2015 The ISL80020, ISL80020A, ISL80015 and ISL80015A are highly efficient, monolithic, synchronous step-down DC/DC converters that can deliver up to 2A of continuous output current from a 2.7V to 5.5V input supply. They use peak current mode control architecture to allow very low duty cycle operation. They operate at either 1MHz or 2MHz switching frequency, thereby providing superior transient response and allowing for the use of small inductors. They have excellent stability. The ISL80020, ISL80020A, ISL80015 and ISL80015A integrate very low r DS(ON) MOSFETs in order to maximize efficiency. In addition, since the high-side MOSFET is a PMOS, the need for a Boot capacitor is eliminated, thereby reducing external ponent count. They can operate at 100% duty cycle (at 1MHz). The device is configured in PWM (pulse width modulation) for fast transient response, which helps reduce the output noise and RF interference. These devices are offered in a space saving 8 pin 2mmx2mm TDFN lead free package with exposed pad for improved thermal performance. The plete converter occupies less than 64mm2 area.
