TEA1832LTS
GreenChip SMPS control IC
[1] Guaranteed by design.
[2] The clamp voltage on the PROTECT pin is lowered when the IC is in Power-down mode. (latched or restart protection).
[3] The Output Short Circuit Protection (OSCP) is only enabled when the voltage level on the ISENSE pin during the secondary stroke is
below V
dis(oscp)ISENSE
level (half the V
ovp(ISENSE)
level). When enabled, the OSCP becomes active when the V
sense
level exceeds
V
th(sense)opp
and the V
sense
level is reached within 1 s (cycle-by-cycle). The switching period is then stretched to 28 s (36 kHz, f
osc
OSCP).
