PIN DESCRIPTION
Pin Number
Symbol
Description
1
SS
Generates a 20- A current source. IC turns or when capacitor is charged to 4.6 V.
2
R
OSC
Sets the oscillator charging current. Use the “oscillator frequency vs. R
OSC
” curve in The Typical Characteristics
section.
3
C
OSC
Sets oscillator frequency. Use the “Oscillator frequency vs. R
” curve in the Typical Characteristics section
along with equations 1 and 2 in the Oscillator section of the Description of Operations.
4
SYNC
Synchronization input overrides the oscillator. Slave mode operations is possible, as is operation of the converter
at duty cycles >50%. See Oscillator section of the Description of Operations.
5
V
Ground or negative mode of input power supply.
6
Vcc
Bootstrap power supply pin
7
I
SENSE
Current-mode sense input
8
S
Switch FET source.
9
D
Switch FET drain.
10
NC
No connect: for test purposes only. (Normally left open)
11
V+
High voltage (up to 200 V) power supply input.
12
SD
Shutdown. Logic low shuts down the controller.
13
V
REF
Output of the 4-V reference sources 5 mA.
14
NI
Non-inverting input of the error amplifier. A resistor divider from the reference can be used to set this voltage.
15
FB
Inverting input to the error amplifier; used to maintain output regulation.
16
Comp
Output of the error amplifier. Used to provide compensation for the converter’s feedback control loop.
