FUNCTION
Power Output. Bypass OUT_ to ground with a 22 F F rated ceramic capacitor. For optimal
performance place the ceramic capacitor as close as possible to OUT_. OUT1 and OUT2
should be shorted together directly under the IC. In True Shutdown, the output voltage can fall
to 0V, but OUT_ has a diode with its cathode connected to IN. See Figure 3.
Input Supply Voltage. Bypass IN to GND_ with a 4.7 F F ceramic capacitor. A larger
capacitance may be required to reduce noise.
Converter Switching Node. Connect a 1 F H inductor from LX_ to IN. LX_ is high impedance in
shutdown. LX1 and LX2 should be shorted together directly under the IC.
Enable Input. Drive EN logic-high to enable boost mode, regardless of the logic level of TREN.
Connect EN to ground or drive logic-low to allow TREN to select either True Shutdown or track
mode. See Table 1.
Ground. Connect GND_ to a large ground plane. GND1 and GND2 should be shorted together
directly under the IC.
Track Enable Input. Drive TREN logic-high to enable track mode. Connect TREN to ground or
drive logic-low to place the IC in True Shutdown. See Table 1.
