SY7102
High Efficiency 1MHz, 2.5A Step Up Regulator
General Description
SY7102 is a high efficiency boost regulator targeted for
general step-up applications. The device integrates a
low RDS(0N) switch to minnimize the conduction loss.
Low output voltage ripple and small external inductor
and capacitor sizes are achieved with 1MHz switching
frequency.

Pin Description
GND
2 Ground pin
LX 1 Inductor node. Connect an inductor between power input and LX pin.
FB 3 Feedback pin. Connect a resistor R1 between V and FB, and a
resistor R2 between FB and GND to program the output voltage:
VOUT=0.6V*(R1/R2+1).
EN 4 Enable control. Pull high to turn on. Do not float.
VDD
5 IC power supply input
NC 6 No connection.
