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 rDS(ON)MOSFETs in order to maximize efficiency.

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 complete converter occupies less than 64mm2area.

The ISL80101-ADJ is a low voltage, high current, single output LDO specified at 1A output current. This LDO operates from input voltages from 2. 2V to 6V, and is capable of providing output voltages from 0. 8V to 5V. The ISL80101-ADJ features an adjustable output. For the fixed output version of the ISL80101-ADJ, please refer to the ISL80101 datasheet. A submicron BiCMOS process is utilized for this product family to deliver the best in class analog performance and overall value. This CMOS LDO will consume significantly lower quiescent current as a function of load compared to bipolar LDOs, which translates into higher efficiency and packages with smaller footprints. State of the art internal compensation achieves a very fast load transient response. An external capacitor on the soft-start pin provides an adjustable soft-starting ramp. The ENABLE feature allows the part to be placed into a low quiescent current shutdown mode. A Power-good logic output signals a fault condition.

A submicron BiCMOS process is used for this product family to deliver best-in-class analog performance and overall value. These CMOS (LDOs) consume significantly lower quiescent current as a function of load over bipolar LDOs, so they are more efficient and allow packages with smaller footprints. The quiescent current has been modestly compromised to enable a leading class fast load transient response, and hence a lower total AC regulation band for an LDO in this category.
