batteries less frequently, a
crucial factor in the mar-
ketability of battery-pow-
ered electronic devices.
By featuring an
ultra-low IQ of 250 nA
(compared with approx-
imately 1 μA for conventional LDOs), the new LDO reduces
standby and/or shutdown current, thereby minimizing power
consumption in battery-powered applications. Power dissipa-
tion in standby mode is a critical factor for remote, battery-op-
erated sensor nodes due to the stringent demands that they
make on battery life and the difficulty in replacing batteries.
The MCP1811 is available in package sizes as small as 1 ×
1 mm, potentially saving developers valuable board space that
can be used for a larger battery.
The MCP1811 also provides faster load line and transient
response compared with other ultra-low-IQ LDOS, allowing
devices like monitors or sensors to wake up more quickly from
sleep or standby modes. Faster transient response times can
help designers avoid undervoltage and overvoltage lockout
measures found in sensitive applications in which transient
spikes can lead to catastrophic results, said Microchip.
Samples are available. Prices start at $0.28 per 10,000 units
in a 1 × 1-mm DFN package. Parts can be purchased via Mi-
crochip’s purchasing portal.

takes aim at RF power
amplifiers
Flex Power Modules, a division
of Flex, recently introduced the
PKB4216HDPI, the newest edition
to its family of DC/DC converters
designed for radio frequency power amplifier (RFPA) appli-
cations in the telecom sector. A descendant of Flex’s 750 W
PKJ4000 series, the PKB-D high-density converter, packaged in
an eighth-brick format, is optimized for high-voltage LDMOS
applications and 50-V GaN-based RFPAs.
The PKB4216HDPI features an input voltage range of 36 V
to 60 V and an output of 50 V at 5 A. A wide-output voltage
adjustment range of 40 VDC to 55 VDC offers developers the
opportunity to optimize the connected RF section, with typical
peak efficiency of 94.5% at 48 Vin and full load.
The PKB-D is available with a baseplate, designed to ensure
conduction cooling in typical RFPA application environments
inside sealed enclosures with no airflow. This allows for full-pow-
er operation at up to 85°C baseplate temperature and an output
of up to 4 A/200 W at 100°C baseplate temperature. The operat-
ing temperature range of the device is –40°C to 125°C.
The PKB4216HDPI features a half-bridge design with the
latest PWM controller technology, ensuring a high level of inte-LDO regulator extends battery life for portable
devices by as much as four times longer
Microchip Technology Inc. recently launched a new linear
low-dropout (LDO) regulator that can extend battery life in mobile
and portable electronic devices by as much as four times longer
than conventional ultra-low-quiescent (IQ) LDOs. The MCP1811
LDO’s ultra-low IQ will allow consumers to recharge and replace28 NEW PRODUCTS Power
