And by using the proposed external components, only 8.3mm2 of printed circuit board area is utilised. Both products offer synchronous rectification and have high and low side MOSFET driver transistors embedded. The main difference between the two products is their output current power. The converters operate in a VFM mode and deliver 100 and 300 A respectively. The chips are designed for wearables and IoT and for applications requiring a low supply voltage, between 0.3 and 1.2 V. the Japanese multinational imaging and electronics company has announced the launch of two Buck DC/DC Converters: the RP516 and RP517. Ricoh Launches DC/DC Converters for ‘Wearables’ “By wasting less standby current, the product can cut battery count by 50%, giving customers the option to use smaller batteries,” TI said. The synchronous step-down converter is designed to draw as little standby current as possible thereby extending battery life. Both non-synchronous converters (integrated high-side FET and external diode) and synchronous converters (integrated high-side and low-side FETs) simplify the design process by reducing the external component count. These offer a balance of flexibility and ease of use. The converters’ feature a controller with one or more integrated FETs and an external inductor. Customers can now use the new DC/DC converter to shrink the overall size of power supply solutions, reduce costs and adopt smaller batteries in their devices. It is designed for use in consumer and industrial Internet of Things (IoT) devices that have limited battery life. US-based Texas Instrument (TI), the largest player in the analogue semiconductor space, has launched its own latest low-power DC/DC ‘Buck’ converter.
Texas Instruments Launches Low-Power DC/DC Converter It offers itself as a super cap charger and mini-laboratory power supply,” explains the company. “The design can be used as a driver for white, infrared and ultraviolet power LEDs, or as a battery charger for lead, NiCd, NiMH or lithium-ion batteries. LEDs on the board indicate: voltage control mode current control mode and missing output voltage. In the two operating modes, the output voltage can be set from 0 to 15 V and the current from 0 to 2.5 A. Based on its ‘MagI☼ VDRM’ (Variable Step-Down Regulator Module) the upgraded design includes two additional control loops. KG, recently upgraded its DC/DC converters. The German manufacturer of electronic and electromechanical components for the electronics industry, Würth Elektronik eiSos GmbH & Co. Würth Elektronik Unveils ‘MagI☼ Power’ DC/DC Converters Key players in the DC/DC converter market include General Electric (GE) (US) Ericsson (Sweden) Texas Instruments (US) Murata Manufacturing Co. Previously and before the development of power semiconductors, the primary way to convert the voltage of a DC supply to a higher voltage was via AC. They are increasingly used in portable electronic devices such as cellular phones and laptop computers. The DC-to-DC converter is a type of electric power converter that converts a source of direct current (DC) from one voltage level to another. What is a DC to DC converter How does it work?ĭC to DC converters that generate a precise and constant current are proving to be a crucial factor in the development of mission-critical electronic components.
