Note 4:
Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.

Note F.
Output duty-cycle is initially determined by V
T1
, as it is greater than V
T2
.
PWM duty-cycle follows V
T1
as it increases.
V
T1
drops below V
T2
. V
T2
now determines the output duty-cycle.
The PWM duty-cycle follows V
T2
as it increases.
Both V
T1
and V
T2
decrease below V
SLP
but above V
IL
. The device enters sleep mode.
The PWM ‘wakes up’ because one of the control inputs (V
in this case) has risen above V
WAKE
. The startup timer is triggered, forcing OUT
high for 64 clock periods. (V
WAKE
= V
SLP
+ V
HYST
. See “Electrical Characteristics.”)
Following the startup interval, the PWM duty-cycle is the higher of V
T1
and V
T2
.
