Absolute Maximum Ratings (T
A = 25°C)
Values beyond absolute maximum ratings can cause the device to be pre-
maturely damaged. Absolute maximum ratings are stress ratings only
and functional device operation is not implied

Storage Temperature
-65°C to +150°C
Operating Temperature
-40°C to +85°C
Lead Temperature

Important Note:
All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are at the
specified temperature and are pulsed tests, therefore: TJ = TC = TA
Electrical Characteristics
VIN = 5V, VOUT = 12V, IOUT = 0mA, FOSC = 600kHz, TA = 25°C unless otherwise specified.

Pin Descriptions
Pin Number
Pin Name
Pin Function
1
PGND
Power ground; connected to the source of internal N-channel power MOSFET
2
SGND
Signal ground; ground reference for all the control circuitry; needs to have only a single connection to PGND
3
RT
Timing resister to adjust the oscillation frequency of the converter
4
EN
Chip enable; connects to logic HI (>1.6V) for chip to function
5
LBI
Low battery input; connects to a sensing voltage, or left open if function is not used
6
LBO
Low battery detection output; connected to the open drain of a MOSFET; able to sink 1mA current
7
SS
Soft-start; connects to a capacitor to control the start of the converter
8
FB
Voltage feedback input; needs to connect to resistor divider to decide VO
9
VDD
Control circuit positive supply
10
LX
Inductor drive pin; connected to the drain of internal N-channel power MOSFET
