Additional Infomation About Product

DATASHEET ISL91127IR FN8859 Rev 1.00 High Efficiency Buck-Boost Regulator with 4.5A Switches August 3, 2016 The ISL91127IR is a high-current buck-boost switching Features regulator for systems using new battery chemistries. It uses Accepts input voltages above or below regulated output Intersils proprietary buck-boost algorithm to maintain voltage voltage regulation while providing excellent efficiency and very low output voltage ripple when the input voltage is close to the Automatic and seamless transitions between buck and output voltage. boost modes The ISL91127IR is capable of delivering at least 2A continuous Input voltage range: 1.8V to 5.5V output current (V = 3.3V) over a battery voltage range of OUT Output current: up to 2A (PVIN = 2.5V, V = 3.3V) OUT 2.5V to 4.35V. This maximizes the energy utilization of High efficiency: up to 96% advanced single-cell Li-ion battery chemistries that have significant capacity left at voltages below the system voltage. 30A quiescent current maximizes light-load efficiency Its fully synchronous low ON-resistance, 4-switch architecture 2.5MHz switching frequency minimizes external component and a low quiescent current of only 30A optimize efficiency size under all load conditions. Fully protected for short-circuit, over-temperature and The ISL91127IR supports stand-alone applications with a fixed undervoltage 3.3V or 3.5V output voltage or adjustable output voltage with 20 Ld 4mmx4mm QFN package an external resistor divider. Output voltages as low as 1.0V or as high as 5.2V are supported. Applications The ISL91127IR is available in a 20 Ld, 0.5mm pitch QFN Handheld and battery powered consumer and medical (4mmx4mm) package. The 2.5MHz switching frequency devices further reduces the size of external components.
