Description

The ISL8002, ISL8002A, ISL80019 and ISL80019A are highlyefficient, monolithic, synchronous step-down DC/DC convertersthat can deliver up to 2A of continuous output current from a 2.7Vto 5.5V input supply. They use peak current mode controlarchitecture to allow very low duty cycle operation. They operateat either 1MHz or 2MHz switching frequency, thereby providingsuperior transient response and allowing for the use of smallinductors. They also have excellent stability and provide bothinternal and external compensation options.The ISL8002, ISL8002A, ISL80019 and ISL80019A integratevery low rDS(ON) MOSFETs in order to maximize efficiency. Inaddition, since the high-side MOSFET is a PMOS, the need for aBoot capacitor is eliminated, thereby reducing externalcomponent count. They can operate at 100% duty cycle (at 1MHz)with a dropout of 200mV at 2A output current.These devices can be configured for either PFM (discontinuousconduction) or PWM (continuous conduction) operation at lightload. PFM provides high efficiency by reducing switching losses atlight loads and PWM reduces noise susceptibility and RFinterference.These devices are offered in a space saving 8 pin 2mmx2mmTDFN lead free package with exposed pad for improved thermalperformance. The complete converter occupies less than0.10in2 area.
