Pin Description
Pin Number(*)
Pin Name
Function
A1
FB
Feedback Analog Input. Connect to the output at the output filter capacitor (Figure 1)
B1
VID1
Output Voltage Control Inputs. Set the output voltage using these digital inputs (see Table
1). The output defaults to 1.5V if these pins are unconnected.
C1
VID0
D1
SYNC/MODE
Synchronization Input. Use this digital input for frequency selection or modulation control.
Set:
SYNC/MODE = high for low-noise 600kHz PWM mode
SYNC/MODE = low for low-current PFM mode
SYNC/MODE = a 500kHz - 1MHz external clock for synchronization to an external clock in
PWM mode. See
Synchronization and Operating Modes in the Device Information section.
D2
EN
Enable Input. Set this CMOS Schmitt trigger digital input high to VDD for normal
operation. For shutdown, set low to SGND. Set EN low during power-up and other low
supply voltage conditions. (See
Shutdown Mode in the Device Information section.)
D3
PGND
Power Ground
C3
SW
Switching Node connection to the internal PFET switch and NFET synchronous rectifier.
Connect to an inductor with a saturation current rating that exceeds the 850mA max
Switch Peak Current Limit specification of the LM2612 (
Figure 1)
B3
PVIN
Power Supply Input to the internal PFET switch. Connect to the input filter capacitor
(
Figure 1).
A3
VDD
Analog Supply Input. If board layout is not optimum, an optional 0.1µF ceramic capacitor
is suggested (
Figure 1)
A2
SGND
Analog and Control Ground
(*) note the pin numbering scheme for the MicroSMD package was revised in April, 2002 to comform to JEDEC standard. Only the pin numbers were revised. No
changes to the physical location of the inputs/outputs were made. For reference purpose, the obsolete numbering has FB as pin 1, VID1 as pin 2, VID0 as pin3,
SYNC as pin 4, EN as pin 5, PGND as pin 6, SW as pin 7, PVIN as pin 8, VDD as pin 9 and SGND as pin 10.
