Bel Power Solutions
DP7007G
is an intelligent, fully
programmable step-down point-of-load DC-DC
converter integrating digital power conversion and
intelligent power management. It works with the
DM7300 Series Digital Power Managers (DPM)
which provides for synchronizing all system Power-
On-Load regulators, for an elegant, flexible, low
noise power system solution.
All key parameters, sequencing, tracking, fault
protection, and compensation parameters of the
DP7007G are programmable via I
2
C based GUI. All
settings can be changed by a user at any time
during product development and service. Once
programmed, the DPM remembers all settings and
configures the DP7007G through a self-clocking
single wire communication bus. FLASH memory in
the DPM allows changes to be made without the
need to solder or rewire the regulator.
Input voltage range: 8 V–14 V
Output voltage range: 0.7 V–5.5 V at 0 – 7 A.
Programmable dynamic output voltage positioning
for better load transient response
Choice of 500 KHz switching for highest efficiency
or 1MHz for lowest ripple noise.
Flexible Fault Response features
Multiple turn-on/off slew rates and delays
Digital Filter Compensation
Synchronous operation with other supplies
Real time performance monitoring
GUI based configuration for short development
time.
Small footprint SMT package: 12.5 x 22.2 x 6.5 mm.
Approved to the latest edition and amendment of
ITE Safety standards, UL/CSA 60950-1 and
IEC60950-1

At negative (sink) output current (bus terminator mode) the efficiency of the DP7007 degrades resulting in increased internal power dissipation and
switching noise. Therefore maximum allowable negative current under specific conditions is lower than the current determined from the de-rating
curves shown in paragraph.

Sequenced Off: The turn-off follows the turn-off delay and slew-rate settings; Critical Off: At turn-off both low and high switches are immediately
disabled; Catastrophic Off: At turn-off the high side switch is disabled and the low side switch is enabled.

Timing based on SD clock and subject to tolerances of SD.
Achieving fast slew rates under specific line and load conditions may require feedback loop adjustment. See Rising and Falling Slew Rates.
For remote sense, it is recommended to place a 0.01-0.1μF ceramic capacitor between +VS and –VS pins as close to the dPOL converter as
possible.
