Function

1
BOOST
The BOOST pin provides additional drive voltage to the on−chip NPN
power transistor. The resulting decrease in switch on voltage increases
efficiency.
2
2, 3, 4
VIN
This pin is the main power input to the IC.
3
5, 6, 7
VSW
This is the connection to the emitter of the on−chip NPN power transistor
and serves as the switch output to the inductor. This pin may be
subjected to negative voltages during switch off−time. A catch diode is
required to clamp the pin voltage in normal operation. This node can
stand −1.0 V for less than 50 ns during switch node flyback.
4
(CS51412/CS51414)
8
BIAS
The BIAS pin connects to the on−chip power rail and allows the IC to run
most of its internal circuitry from the regulated output or another low
voltage supply to improve efficiency. The BIAS pin is left floating if this
feature is not used.
5
(CS51411/CS51413)

SYNC
This pin provides the synchronization input.

SHDNB
Shutdown_bar input. This is an active−low logical input, TTL compatible,
with an internal pull−up current source. The IC goes into sleep mode,
drawing less than 85 mA when the pin voltage is pulled below 1.0 V. This
pin may be left floating in applications where a shutdown function is not
required.
6
13
GND
Power return connection for the IC.
7
16
VFB
The FB pin provides input to the inverting input of the error amplifier. If
VFB is lower than 0.29 V, the oscillator frequency is divided by four, and
current limit folds back to about 1 A. These features protect the IC under
severe overcurrent or short circuit conditions.
8
17
VC
The VC pin provides a connection point to the output of the error
amplifier and input to the PWM comparator. Driving of this pin should be
avoided because on−chip test circuitry becomes active whenever
current exceeding 0.5 mA is forced into the IC.
