Description THV3012 is a synchronous buck switching regulator IC with the external High side Power MOSFET. Available high current power supply using a mini- mum number of external components, because any external phase compensation parts are not necessary. The bootstrap technology provides high efficiency more than 97%. Utilizing the latest and THine’s unique architecture, THV3012 achieves ultra quick transient response. Soft start by SS pins makes constant and stable soft start curve not depend on the load fluctuation. THV3012 also has the Power-good function and the Off-delay function to facilitate the setting of On/Off sequence. Features • Synchronous rectifier DC/DC converter • Wide input voltage range : VIN = 4.5V~ 28V VCC = 4.5V~5.5V • Output voltage range : 0.85~4.0V • Large Load current (dependent on external FET) • Ultra quick transient response • Feed back voltage accuracy : 1% • 360kHz/500kHz programmable oscillation frequency • Over current protection • Short circuit protection (latch function) • Undervoltage lockout function • Power-good function • Off Delay function • Programmable soft start • Thermal shutdown • Small 4.4x5mm body TSSOP 16pin 1ch DC/DC converter. THV3012 Applications • Micro processor core/ASIC/FPGA/DSP/DDR SDRAM/DDRII SDRAM power supply Typical Applications CTL input Input Power Good output LG LL BOOT VIN HG CTL PSI VCC PGOOD FSET SS OFFDELAY FB CSN CSP GND PSI input Output VCC input |
