Product Summary
The SCI7661COA is a DC-DC Converter features high operational performance with low power dissipation. It consists of two major parts: the booster circuitry and the regulator circuitry. The booster generates a doubled output voltage (-2.4 to -12V) or tripled output voltage (-3.6 to -18V) from the input (-1.2 to -6V). The SCI7661COA is capable of setting the output to any desired voltage. The regulated voltage can be given one of the three threshold temperature gradients.
Parametrics
SCI7661COA absolute maximum ratings: (1)Input supply voltage, VI: -20/n to 0.5V; (2)Input terminal voltage, VI: VIN-0.5 to 0.5V; VOUT-0.5 to 0.5V; (3)Output voltage, VO: -20V; (4)Allowable loss, PD: 300mW; (5)Operating temperature, TOPR: -30 to 85℃; (6)Storage temperature, TSTG: -55 to 150℃; (7)Soldering temperature and time, TSOL: 260℃.
Features
SCI7661COA features: (1)High performance with low power dissipation; (2)Simple conversion of VIN (–5V) to |VIN| (+5V), 2 |VIN| (+10V), 2VIN (–10V) or 3VIN(–15V); (3)On-chip output voltage regulator; (4)Power conversion efficiency–Typ. 95%; (5)Temperature gradient for LCD power supply -0.1% /℃, 0.4%/℃ or 0.6%/℃; (6)Power off by external signals -Stationary current at power off -Max. 2 mA; (7)Cascade connection–two device connected: VIN=–5V, VOUT=–20V; (8)On-chip C’–R oscillator.
