Step-down regulator delivers 2 A from tiny 6.25 x 4-mm BGA package
The LTM8063 from Analog Devices is a 40VIN, 2A µModule step-down regulator in a tiny 6.25mm x 4mm BGA package. According to the company, the package size is 75% smaller than the existing equivalent product. With two 0805 size capacitors and two 0603 size resistors, the solution is only 70mm². The Silent Switcher architecture minimizes EMI emissions, enabling the […]
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 […]
Step-down regulator supports N+1 current sharing
Analog Devices, Inc. is now offering the LTM4645, a 25A step-down regulator with the ability to current share multiple independent devices (N) where at least one LTM4645 is used as backup (+1) to ensure power availability if one device in this N+1 arrangement detects a fault and must be disconnected. For example, a 75A, 1V load […]
Step-down 5-V regulator handles noisy 40-V inputs
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTM8065, a µModule (power module) step-down regulator with up to 40V input voltage (42V abs max), which can safely operate from unregulated or fluctuating 12V to 36V input supplies in noisy environments such as industrial robotics, test and measurement, medical, factory automation and avionics systems. […]
ZVS buck regulators provide 20 A
Vicor today announced that it has extended its Cool-Power 48V ZVS 20A buck regulator portfolio by releasing the PI3523-00-LGIZ (PI3523). The PI352x family offers 20A solutions complementing the previously released 10A 48VIN PI354x family, enabling scalable power options for 48V direct to point-of-load (PoL) applications. The PI3523 is a 48VIN, 3.3VOUT nominal Buck Regulator capable […]
Regulator generates –26.5 to –0.5 V output from positive-input supply
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTM4651, a nonisolated inverting output µModule regulator that can generate –26.5V to –0.5V output from a positive input supply voltage. The LTM4651 operates over a 3.6V to 58V input voltage range and is housed in a 15mm x 9mm x 5.01mm BGA package, a compact […]
CMOS LDO regulators target mobile apps
Toshiba America Electronic Components, Inc. (TAEC) today announced a new family of CMOS low dropout (LDO) regulators: the TCR4DG series. Consisting of general-purpose, single-output voltage regulators with on/off control input, low output noise voltage and low inrush current, the TCR4DG series is available in fixed output voltages between 1.0V and 4.5V – capable of driving […]
Step-down switch regulator needs no exta surge suppression
Analog Devices, Inc. announces the LTC7103, a 2.3A, 105V input capable synchronous step-down switching regulator. Its wide 4.4V to 105V input voltage range is designed for operation from a continuously high voltage input source or from an input that has high voltage surges, eliminating the need for external surge suppression devices. This makes the LTC7103 […]
Next-gen dc switching regulators handle up to 1 A with 96% efficiency
CUI’s Power Group today announced the addition of four new series to its family of non-isolated dc switching regulators. The next generation VX78‑500, VXO78‑500, VX78‑1000, and VXO78‑1000 series are extremely efficient, typically up to 96%, and balance maximizing economy while delivering a high level of performance as a direct alternative to using linear regulators. Utilizing […]
