Series
3 AMP HIGH-PERFORMANCE ADJUSTABLE ISR
Single-Device 5V to 3V Power 85% Efficiency Small SIP Footprint:
0.36" x 2.00” x 0.60"(H) Wide Input Voltage Range:
+4.5V to +9.0V Internal Short Circuit Protection Over-Temperature Protection
The PT6305N is Power Trends’ new high performance +5V to +3.3V, 3
Amp, 12-Pin SIP (Single In-linePackage) Integrated Switching
Regulator (ISR). This high-performance ISR allows easy integration of low-power 3.3V logic IC’s into existing 5V systems without redesigning the central power supply. Only one external capacitor is required for proper operation. The PT6306,7,8 can be used to power high-speed data buses (+2.1V), or the new GTL (+1.2V) logic buses.
