Buck-boost regulator targets mobile platforms using reversible USB Type-C connectors
The ISL95338 buck-boost voltage regulator for tablets, ultrabooks, power banks, and other mobile devices using the reversible USB Type-C connector. Intersil’s new bidirectional voltage regulator accepts input power from a wide range of DC power sources — AC/DC power adapters, USB power delivery (PD3.0) ports, travel adapters, power banks — and converts it to a […]
42-V single-channel DC/DC step-down power module delivers up to 15 A continuously
Intersil, a subsidiary of Renesas Electronics Corporation, announced the first 42V single-channel DC/DC step-down power module that delivers up to 15A of continuous current. The ISL8215M operates from a single wide input voltage range that includes industry standard 12V, 18V, and 24V intermediate bus power rails. The module offers adjustable output voltages from 0.6V to […]
PMIC delivers 91% efficiency at 1.1 V output voltage for space/power constrained systems
Intersil, a subsidiary of Renesas Electronics Corporation, introduced a highly integrated programmable power management IC (PMIC) that delivers 91% efficiency at 1.1V output voltage for application processors, GPUs, FPGAs and high-performance system power. The new PMIC’s low RDS(on) MOSFETs and programmable PWM frequency allows designers to use fewer low-profile external components, enabling a 50mm2 power-supply […]
Synchronous buck regulators and overcurrent protection (OCP)
by Haifeng Fan, Intersil, a subsidiary of Renesas Electronics Synchronous buck regulators are widely used in industrial and infrastructure applications to step down 12V rails to point-of-load inputs as low as 0.6V for microcontrollers, FPGAs, memory and peripheral I/Os. Overcurrent protection (OCP) is essential to protect these switching regulators from damage by excessive current. Cycle-by-cycle current […]
Sync buck regulators step down inputs to just 0.6 V
Intersil, a subsidiary of Renesas Electronics Corporation (TSE: 6723), today introduced five synchronous buck regulators that step-down 12V rails to point-of load inputs as low as 0.6V for MCUs, FPGAs, memory and peripheral I/Os. The newest members of the ISL850xx family consist of the ISL85014, ISL85012, ISL85009, ISL85005A and ISL85005 buck regulators. They deliver 14A, […]
Charger extends battery life with low 3 μA leakage current in eCall systems
Intersil Corporation announced the ISL78693, a 3.6V single-cell battery charger that extends the life of Lithium Iron Phosphate (LiFePO4) batteries used in automotive emergency call (eCall) systems. The ISL78693 battery charger offers up to 4x lower leakage current (3uA) than competitive chargers, allowing the eCall backup battery to remain charged for a longer period of time. […]
Single-Chip USB-C buck-boost battery chargers support bidirectional power
Intersil Corporation today introduced two new USB-C™ buck-boost battery chargers that support bidirectional power delivery in ultrabooks, tablets, power banks and other mobile products. The single-chip ISL9238 and ISL9238A battery chargers replace competitive two-chip solutions to reduce customer bill of materials (BOM) costs by up to 40%. Both ICs employ Intersil’s patented R3™ modulation technology to […]
Six-Phase bidirectional dc/dc controller optimized for 12-48-V vehicle power systems
Intersil Corporation today announced it is shipping the industry’s first 6-phase bi-directional PWM controller designed to perform buck and boost power conversions between 12V and 48V automotive buses. A single automotive-grade ISL78226 delivers up to 3.75kW at greater than 95% conversion efficiency, and is able to interleave in a modular master/slave architecture to deliver higher power. […]
