The HTB7212 is a high efficiency lowcost off-line constant voltage regulator for Buck and Buck- Boost topology with650V MOSFET.
HTB7212 can output 12V defaultvoltage with few external components, which decreases the system cost. In lightload condition, HTB7212 operates in green mode, in which the inductor peakcurrent and the switching frequency is lower than that of full load to improvethe system efficiency and the reference voltage is decreased to ensure goodload regulation.
HTB7212 has multi-protection functions whichlargely enhance the safety and reliability of the system, including VDDunder-voltage lockout (UVLO), short circuit protection (SCP), pulse-by-pulsecurrent limit, over load protection (OLP) and over-temperature protection(OTP).
