FEATURES
DESCRIPTION
The LM10010 is a precision, digitally programmed
2
• Output Current Accuracy (-40°C to +125°C)
device used to control the output voltage of a DC/DC
• Input Voltage Range: 3V to 5.5V
converter. The LM10010 outputs a DC current
• 6-Bit Current DAC That Connects Directly to
inversely proportional to a 6-bit input word. This
the Feedback Node of an External Regulator to
current DAC output connects to the feedback pin of a
regulator in order to adjust its output voltage to a
Provide Output Voltage Control
desired range and resolution set by the user. As the
• Precision Enable to Support Custom UVLO
6-bit word counts up, the output voltage is adjusted
• WSON-10 3 mm x 3 mm Footprint, 0.5 mm
higher based on the setting of the feedback resistors
Pitch
in the converter.
• Compatible With the TMS320C66XX DSP Smart
The LM10010 is designed to program point of load
Reflex Technology
regulators with adjustable resistor feedback networks
for VID (Voltage Identification).
