gration for low component count and high reliability (up to 10.68 Mhrs). Implement-
ing synchronous rectification also contributes to the device’s high power density.
The PKB-D provides protection against short-circuits, overloads, overtemperature,
and output overvoltage and input undervoltage. The device also features a remote on/
off control with optional positive or negative logic. Startup into pre-biased loads is
guaranteed, and the isolation rating from primary to secondary is 2,250 VDC.
The PKB4216HDPI is available in OEM production quantities.

GaN FET power stages support applications up to 10 kW
Texas Instruments Inc. (TI) recently released several 600-V gallium-nitride (GaN) 50-
mΩ and 70-mΩ power stages to support applications up to 10 kW. The new LMG341x
family allows designers to create smaller designs that are more efficient and offer
higher performance as compared to silicon
field-effect transistors (FETs) in AC/DC
power supplies, robotics, renewable energy,
grid infrastructure, telecom, and personal
electronics applications, said the company.
The portfolio of GaN FET devices,
which the company said is backed by 20
million hours of reliability testing, offers
an alternative to traditional cascade and standalone GaN FETs. By integrating func-
tional and protection features, TI simplifies design, enabling greater system reliability
and higher performance of high-voltage power supplies.
Each device offers a GaN FET, driver, and protection features at 50 mΩ or 70 mΩ
to provide a single-chip solution for applications ranging from sub-100 W to 10 kW.
The LMG3410R050, LMG3410R070, and LMG3411R070 devices come complete
with integrated <100-ns current limiting and overtemperature detection and protect
against accidental shoot-through events. They also prevent thermal runaway and,
with the help of system interface signals, facilitate self-monitoring.
The GaN power stage doubles power density and claims to reduce losses by 80%
compared to silicon MOSFETs. The devices switch frequencies at a rate of 1 MHz and
have a slew rate of up to 100 V/ns.
The LMG3410R050, LMG3410R070, and LMG3411R070, available in 8 × 8-mm
split-pad, QFN packages, are priced at $18.69, $16.45, and $16.45, respectively, in
quantities of 1,000.

Dialog debuts first nanopower PMICs for IoT
Dialog Semiconductor PLC has launched its first fully integrated nanopower power
management ICs (PMICs) for IoT applications. Building on the nanopower family,
the new DA9070 and DA9073 PMICs target low-power IoT applications such as fit-
ness trackers, smartwatches, and smart-home products. These always-on applications
place bigger challenges on a device’s battery life.
“With board area already at a premium for engineers, new power management
solutions are increasingly favored over increasing battery capacity,” said Dialog.
As a result, Dialog developed the nanopower PMICs that extend battery life by
drawing <1-uA quiescent current for each of its step-down regulators that power
always-on components within the system. In addition, the devices combine all key
power management functions to reduce board area by 25% compared to discrete reg-
ulators. Another key feature is the option of creating a battery fuel gauge solution with
the DA9070 using the integrated voltage and current monitors.
