| For assistance or to order, call (800) 531-5782 PT6305 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.

This data is considered typical data for the ISR. Note 2: Minimum Vin data is typical and is not guaranteed. The data corresponds to a 2% output voltage drop. Note 3: Thermal derating graphs are developed in free air convection cooling of 40-60 LFM with no optional heat tab soldered in a printed circuit board. (See Thermal Application Notes).
