PIN FUNCTIONS
V IN (V)
3530 G17
R T (Pin 1): Programs the Frequency of the Internal Oscil-
lator. Connect a resister from R T to ground.
f(kHz) = 33,170/R T (k Ω )
BURST (Pin 2): Used to Set the Automatic Burst Mode
Threshold. Connect a resistor and capacitor in parallel
from this pin to ground. See the Applications Information
section for component value selection. For manual control,
ground the pin to force Burst Mode operation, connect to
V IN to force ?xed frequency PWM mode.
SW1 (Pin 3): Switch Pin Where the Internal Switches A and
B are Connected. Connect inductor from SW1 to SW2. An
optional Schottky diode can be connnected from SW1 to
ground for a moderate ef?ciency improvement. Minimize
trace length to keep EMI down.
SW2 (Pin 4): Switch Pin Where the Internal Switches C
and D are Connected. For applications with output voltages
over 4.3V, a Schottky diode is required from SW2 to V OUT
to ensure the SW pin does not exhibit excessive voltage.
