The power management IC (PMIC) is often a vital part of the lower-voltage DC subsystem, as circuits have multiple power rails with tight individual specifications as well as mandated relationships among them. Part 1 of this FAQ discussed the need for, PMICs and their general characteristics. Part 2 now looks at specific ICs which implement […]
Power Management ICs, part 1: PMIC functions
The power management IC (PMIC) is often a vital part of the lower-voltage DC subsystem, as circuits have multiple power rails with tight individual specifications as well as mandated relationships among them. It’s one thing to develop needed low-voltage DC rails via DC/DC converters or regulators, but there’s also a need to manage these power […]
Step-down regulator module targets data center apps with on-board memory
Analog Devices, Inc. (ADI) expanded its suite of Power by Linear µModule regulators with the LTM4700 step-down DC/DC power regulator, which combines the highest power in its class with the energy efficient performance needed to reduce data center infrastructure cooling requirements. Configured as dual 50A or single 100A configuration, the new power µModule’s innovative package technology enables an increasing […]
Compact synchronous silent switcher provides 5 V, 10 A
Analog Devices announces the Power by Linear LTC3310S, a 5V, 10A low EMI monolithic synchronous buck converter. The device’s fixed frequency peak current mode architecture is ideal for high step-down ratio applications that demand fast transient response. The LTC3310S uses the Silent Switcher 2 architecture with integrated hot loop bypass capacitors to deliver a highly efficient, small footprint […]
Nonsynchronous boost controller that drives two MOSFET stages
Analog Devices announces the Power by Linear LTC7840, a 2-phase nonsynchronous boost controller that drives two stages of external N-channel power MOSFETs. It is configurable as single or dual output boost regulator or for higher voltages, the output of the first channel can feed the input of second channel allowing an output voltage which exceeds several […]
FAQ: Piezoelectric motors, Part 2: drive circuits
Unlike better-known electromagnetic motors, the widely used piezoelectric-based motor/actuator provides precise, repeatable linear motion over short distances, and requires a voltage drive rather than a current drive. Part 1 of this FAQ looked at the moving piezoelectric element of the actuator. Part 2 looks at their drive requirements, which are very different than those of […]
FAQ: Piezoelectric motors, Part 1: actuators
Unlike better-known electromagnetic motors, the widely used piezoelectric-based motor/actuator provides precise, repeatable linear motion over short distances, and requires a voltage drive rather than a current drive. When we think “motor”, we usually think of rotating motion or perhaps a special “linear motor” which is a rotary motor which has been rolled out flat. To […]
Super-low-voltage supervisors feature ±0.5% reset threshold accuracy for ASIC, FPGA, DSP, MCU, MPU architectures
Analog Devices announces the Power by Linear LTC2962-LTC2964 family of highly accurate 4-channel voltage supervisors for increased system voltage margin and enhanced reliability. ASIC, FPGA, DSP, MCU and MPU architectures that operate from supplies as low as 1V cannot utilize traditional 1%-2% accurate voltage supervisors without shedding valuable system voltage margin and shrinking the remaining load […]
Optocouplers, Part 2: Parameters and applications
Part 1 of this FAQ explored the basics of the optocoupler. This part looks at key parameters and some application examples. Q: What are the primary factors used when assessing an optocoupler? A: While there are many important factors, there are several which are noteworthy: isolation, current-transfer ratio (CTR), linearity (for analog use), and speed. […]
Step-down ultrathin regulator module handles ASIC, FPGA loads
Analog Devices announces the Power by Linear LTM4686, a dual 10A or single 20A ultrathin step-down µModule regulator with a PMBus interface housed in a 16mm x 11.9mm x 1.82mm LGA package. The 1.82mm package height allows the LTM4686 to be placed on a PC board very close to its load such as an FPGA or […]
