nalog D vices, Inc., which recently
alog Devices Inc
acquired Linear Technology Corporation, has announced the LTM8063, a 40VIN
, 2A
µModule step-down regulator in a tiny 6.25mm x 4mm BGA
With two 080 h two 0805 size
capacitors and two 0603 size resistors, the
solution is only 70mm². The Silent Switcher
architecture minimises EMI emissions, enabling the LTM8063 to pass the CISPR 22 class B
EMC standard. This device can
deliver 2A (2.5A peak) of continuous output current from 12VIN 5VOUT at an ambient
to
equivalent product.
temperature of 85°C. Its 40V input voltage allows it to safely operate from unregulated or fluctuating 12V to 24V input supplies in noisy environments such as avionics, factory automation and industrial robotics. The output voltage is adjustable with one resistor from 0.8V to 15V.

USB-C BUCK-BOOST VOLTAGE REGULATOR
I c b t a r T a r
Intersil has released, what it is claiming is the industry’s first buck-boost voltage regulator for tablets, ultrabooks, power banks, and other mobile devices using the reversible USB Type-C connector. This 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 regulated voltage up to 24V. The ISL95338 can also convert a wide range of DC power sources to a regulated 20V at its power adapter input. The ISL95338 supports the USB-C ecosystem with buck-mode, boost-mode, and buck-boost mode, and is flexible enough to use in any USB-C power management application.
This single-chip device replaces two voltage converters currently used for
bidirectional buck and boost modes to reduce bill of materials (BOM) cost by 50%. It leverages Intersil’s R3 modulation technology to deliver acoustic noise- free operation, light-load efficiency and ultra-fast transient response. Intersil’s R3 extends battery life by combining the best features of fixed- frequency pulse width modulation (PWM) and hysteretic PWM to maximise power efficiency. The ISL95338 is also USB 3.1-compliant and provides serial communication through SMBus/I2
C, allowing designers to program several MEDICALLY APPROVED DC:DC CONVERTERS
Gresham Power Electronics has released two new series of DC-DC converters from Polytron Devices that are approved for use in medical applications including equipment and devices used in close proximity to patients. Both series are in the industry standard miniature DIP Package and
provide a regulated 3watt output with the TWA3/MHI featuring a 2:1 wide input voltage range while the TWB3/MHIA5 Series has an ultra-wide 4:1 input voltage range. Both provide regulated single or dual output voltages over the range 3.3 to 24VDC or +/-5 to +/15VDC and have input voltage options from 4.5 to 72VDC. Polytron DC-DC converters can be supplied for through-hole printed circuit board mounting or surface mount form for automated assembly. Standard features include, High Efficiency up to 89%, operating temperature range -40 to 1050
C (with derating), reinforced Insulation,
clearance and creepage distance 8.0 mm/2MOPP, 5000VAC input to output 2MOPP Isolation, 2µA patient leakage current, built-in EMI Class A filter, medical safety approvals including: UL, CE and ANSI/AAMI ES60601-1, EN60601-1 and IEC60601-1, ROHs Compliant to 2011/65/EU. Typical applications include diagnostic and therapy equipment, Home
equipment including nebuliser and blood pressure monitors, X-ray machines, surgical tools with lights, lasers and video microscopes, defibrillators, medical devices and equipment, portable ventilators and 3D laparoscope.

input/output current and voltage slew rate settings for a customised solution. The ISL95338 is fully compliant to the USB PD3.0 standard and supports
programmable power supply (PPS) fast charging with bidirectional 5V to 20V buck, boost or buck-boost modes. Multiple ISL95338 ICs can be combined with the ISL95521A combo battery charger or ISL9238 buck-boost battery charger to enable simultaneous multiport USB-C charging. The ISL95338 can also be used with the R9A02G011 USB PD controller and RAJ240045 fuel gauge IC for a complete USB-C power delivery solution.

2MOPP 1-WATT DC/DC CONVERTER
general IEC 62368-1 equipment safety standards. The series is covered by a CB Test Report, which simplifies access to international markets.
The Recom REM1 series, now available from Dengrove Electronic Components, is a 1-Watt DC/DC converter family certified to medical IEC/EN/ANSI/AAMI 60601-1 and
The converters provide two means of patient protection (2MOPP), with 250V working voltage, 5.2kV/1- minute isolation, and 8mm creepage and clearance, within the 19.6mm x 6.0mm x 10.2mm outline. Input-voltage options are 3.3V,
5V, 12V, 15V, or 24V, and the output can be 3.3V, 5V or 12V.
