THV6511 Datasheet, PDF (7/9 Pages) THine Electronics, Inc. – THV6511 is a 1 channel boost converter IC

THV6511_Rev.1.00_E
If C_SS is too small or not present at all, the internal soft
start circuit ensures that the soft start period is at least
3.4ms.
Over current protection (OCP)
In order to restrict the over-current by the abnormalities
of load, etc., the over-current protection circuit is built in.
Over-current detection of pulse-by-pulse system is
adopted. An output transistor is turned off if the current
which flows into an output transistor reaches boost
converter limit current (Ilim). An over-current protection
circuit detects the peak current of an inductor.
Input-and-output voltage and ripple current is taken into
consideration.
Thermal shut down (TSD)
In order to prevent destruction by heat, the thermal
shutdown circuit is built in. If the junction temperature
Tj is 125^oC or more, the thermal shutdown circuit will
operate and it will stop switching operation. Moreover,
the hysteresis of a thermal shutdown circuit is 20^oC. If Tj
falls, output voltage will return.
