SP6120HVCY_TR

The SP6120HVCY_TR is one member of the SP6120HV series.The SP6120HV is a fixed frequency, voltage mode, synchronous PWM controller designed to work from a single 12V, 5V or 3.3V input supply. Sipex's unique "AnyFET Technology allows the SP6120HV to be used for resolving a multitude of price/performance trade-offs.It is separated from the PWM controller market by being the first controller to offer precision,speed, flexibility, protection and efficiency over a wide range of operating conditions.

Features of the SP6120HVCY_TR are:(1)optimized for single supply, 3V - 12V applications; (2)high efficiency: greater than 95% possible; (3)"AnyFET  technology: capable of switching either PFET Or NFET high side switch; (4)selectable discontinuous or continuous conduction mode; (5)fast transient response from  window comparator ; (6)16-pin TSSOP, small size; (7)accurate 1% reference over line, load and temperature; (8)accurate 10% frequency; (9)accurate, rail to rail, 43mV, over-current sensing; (10)resistor programmable frequency; (11)resistor programmable output voltage; (12)low quiescent current: 950A, 10A in shutdown; (13)hiccup over-current protection; (14)capacitor programmable soft start; (15)guaranteed boost voltage to enhance high side NFET.

The absolute maximum ratings of the SP6120HVCY_TR can be summarized as:(1)Vcc:13.2 V;(2)BST:19V;(3)storage temperature:-65 to 150;(4)lead temperature (soldering 5s):300;(5)junction temperature:125.These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.When the converter enters a fault mode, the driver holds the high side and low side MOSFETs off for a finite period of time. Provided the part is enabled, this time is set by the discharge of the SS capacitor. The discharge time is roughly 10 times the charge interval thereby giving the power supply plenty of time to cool during an over current fault.  The driver off-time is predominantly determined by the discharge time.Restart will occur just like a normal soft start cycle.
