The ISL8002B is a highly efficient, monolithic, synchronous step-down DC/DC converter that can deliver up to 2A of continuous output current from a 2. 7V to 5. 5V input supply. It uses peak current mode control architecture to allow very low duty cycle operation. ISL8002B operates at a 2MHz switching frequency, thereby providing superior transient response and allowing for the use of a small inductor. ISL8002B also has excellent stability. The ISL8002B integrates very low rDS(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 component count. The device can be configured for either PFM (discontinuous conduction) or PWM (continuous conduction) operation at light load. PFM provides high efficiency by reducing switching losses at light loads and PWM for fast transient response, which helps reduce the output noise and RF interference. The device is offered in a space saving 8 Ld 2mmx2mm TDFN Pb-free package with exposed pad for improved thermal performance. The complete converter occupies less than 64mm2 area.
