  • Over-Temperature Protection The PT6610 series is a high per- formance +5V family of 14-Pin SIP (Single In-line Package) Integrated Switching Regulators (ISRs), designed for stand alone operation in applica- tions requiring as much as 9A of output current. Only two external capacitors are required for proper operation. Please note that this product does not include short circuit protection.

T he input capacitance must be rated for a minimum of 1.1Arms of ripple current. See the application note, PT6500/6600 Series Capacitor Recommendations. (2)ISR will operate down to no load with reduced specifications. (3) For operation below 0°C, use tantalum capacitors for C IN and COUT.
