• Programmable Closed Loop Soft Start
Design Examples
25
• Overcurrent Protection
• 700-mV Reference (TPS40210)
• 263-mV Reference (TPS40211)
The TPS40210 and TPS40211 are wide-input voltage
• Low Current Disable Function
(4.5 V to 52 V), non-synchronous boost controllers.
They are suitable for topologies which require a
grounded source N-channel FET including boost,
• LED Lighting
flyback, SEPIC and various LED Driver applications.
• Industrial Control Systems
The device features include programmable soft start,
overcurrent
protection
with
automatic
retry
and
• Battery Powered Systems
programmable oscillator frequency. Current mode
control provides improved transient response and
simplified loop compensation. The main difference
between the two parts is the reference voltage to
which the error amplifier regulates the FB pin.
