Description
1
N/C
Not Used
2
SD
Shuts down the IC completely and decreases current consumed by the IC to <1
A.
3
PWM/PSM
Logic high = PWM mode, logic low = PSM mode. In PSM mode, synchronous rectification is disabled.
4, 5, 6
V
IN/OUT
Input node for buck mode and output node for boost mode.
7
SYNC
Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization.
If not used, the
pin must be connected to V
DD
, or logic high.
Low power controller ground
8
GND
9
V
REF
FB
1.3-V reference. Decoupled with 0.1- F capacitor.
10
Output voltage feedback connected to the inverting input of an error amplifier.
11
COMP
Error amplifier output for external compensation network.
12
Rosc
External resistor to determine the switching frequency.

V
O
V
S
PGND
Input supply voltage for the analog circuitry. Input voltage range is 2.7 V to 6 V.
14
Direct output voltage sensing to control peak inductor current in PSM mode.
15
Supply voltage for the internal MOSFET drive circuit.
16, 17
Power ground.
18
MODE
Determines the converter topology. Connect to AGND for buck or V
DD
for boost.
