DIO6905E
2 A, Synchronous, Step-Down Converter
Features
Descriptions
1.8 MHz switching frequency
The DIO6905E is
a
monolithic, step-down,
EN for power sequencing
Wide 2.3 V to 5.5 V operating input range
Output adjustable from 0.6 V
Up to 2 A output current
120 mΩ and 80 mΩ internal power MOSFET
switches
switch-mode converter with built-in, internal
power MOSFETs. It achieves 2 A of output
current from a 2.3 V to 5.5 V input voltage with
excellent load and line regulation. The output
voltage can be regulated as low as 0.6 V.
Output discharge
The constant-on-time control scheme provides a
fast transient response and eases loop
stabilization. Full protection features include
cycle-by-cycle current limiting and thermal
shutdown.
Short-circuit protection (SCP) with hiccup
mode
Stable with low ESR output ceramic
capacitors
Available in SOT563 and DFN2*2-8 packages
100% duty cycle
The DIO6905E is available in SOT563 and
DFN2*2-8 packages and requires
a minimal
number of readily available, standard, external
components.
Applications
The DIO6905E is ideal for a wide range of
applications, including high-performance DSPs,
wireless power, portable and mobile devices, and
other low-power systems.
Wireless/Networking cards
Portable and mobile devices
Battery-powered devices
Low-voltage I/O system power
Solid-state drives (SSDs)
