Step-Up (Boost) Regulators

Step-Up (Boost) Regulators

Analog Devices manufactures a broad line of high performance, step-up boost switching regulator ICs and boost switching controller ICs with both synchronous and nonsynchronous switches. These switching voltage regulators offer typical input voltage capability from less than 2 V up to 100 V+, switching frequencies up to 4 MHz, and high efficiency operation up to 96%. With burst mode operation, quiescent currents in the tens of micro-amps level can be attained. This combination of features allows for very small, low profile boost switching regulator circuit implementations with minimum external components. Many of these products can also be configured as SEPIC regulators or flyback topology switching regulators.

µModule Boost Regulators

Analog Devices boost µModule^® (micromodule) regulators are complete system-in-package (SiP) power management solutions with integrated dc-to-dc controllers, power transistors, input and output capacitors, and compensation components within a compact, surface-mount BGA or LGA package. Boost µModule regulators effectively address the needs of engineers facing time and space constraints, yet who are in need of a highly efficient and reliable power management solution.

Boost Regulators with Digital Power System Management

Analog Devices boost regulators with digital power system management (PSM) provide accurate information about power systems and autonomously control and supervise dozens of voltages with ease. They provide high accuracy programming and telemetry with on-board EEPROM parameters that include voltage and current, sequencing, operating frequency, margining, faults, and temperature. Our devices are supported by LTpowerPlay^®, a powerful and intuitive Windows-based development software tool used to configure and interrogate PSM devices. When deployed, PSM devices are seamlessly integrated with existing embedded systems and architectures.

External Power Switch Boost Controllers

Analog Devices manufactures a broad range of step-up (boost) controllers for virtually any application. These controllers offer wide input voltage ranges and multiple output capability, and they can be configured for flyback, forward, or SEPIC converters. Furthermore, they offer burst-mode operation for high efficiencies at light loads and easy synchronization to an external clock, while possessing comprehensive protection features.

Internal Power Switch Boost Regulators

Analog Devices manufactures a broad line of high performance step-up (boost) switching regulators with both synchronous and nonsynchronous internal switches. These regulators offer typical input voltage capability from 0.5 V to 75 V, switching frequencies up to 8 MHz, and high efficiency operation up to 95%. This combination of features allows very small circuit implementations and optimizes battery run time in battery-operated handheld devices.

Micropower Boost Regulators

Analog Devices micropower monolithic step-up (boost) converters are optimized for applications that need to maximize efficiency at very light loads. In addition to very wide input and output voltage ranges, these boost regulators offer synchronous rectification, integrated Schottky diodes, output disconnect, and greatly reduced conducted/emitted EMI. They are an ideal choice for single cell alkaline or lithium-ion powered devices, as well as industrial, medical, or automotive applications.

Multiple Output Boost Regulators

Analog Devices offers a line of high performance multiple output boost/inverting converters. These regulators have internal switches, and offer input voltages from 1.2 V up to 40 V, switching frequencies up to 3 MHz, and high efficiency operation up to 95%. They are configured in dual boost, boost and inverter, or triple and quad output combinations ideally suited for TFT-LCD panels.
