PSR1-78xxS PSR1-SERIES Rev.11-2010 1000mA Switching Regulator Wide Input - Step down SIP3 Plastic Package Non-Isolated & Non-Regulated Short Circuit Protection High Efficiency Mainzer Straße 151–153 D-55299 Nackenheim Tel. +49 6135 7026-0 Fax: +49 6135 931070 www.peak-electronics.de [email protected] The PSR1-S series is a family of cost effective 1.5~5W single output buck DC-DC converters. These converters are encapsulated in a non-conductive black plastic package 3-pin SIP case, continuous short circuit protection with automatic restart and good line / load regulation. Devices are filled up with flame retardant resin .Input voltages of 4.75~18,and 6.5~18 with output voltage of 1.5, 1.8, 2.5, 3.3, 5, Vdc. High performance features include high efficiency operation up to 94%. Standard features include an input range of 4.75~18Vdc tolerance and low output ripple and noise. All specifications typical at Ta=25°C, nominal input voltage and full load unless otherwise specified Input Specifications Voltage Range Filter Input Reflected Ripple Current Wide Input (See Table) Capacitors 40mA pk-pk Output Specifications Voltage Accuracy Short Circuit Protection Line Regulation Load Regulation (10% - 100% load) Ripple and Noise (20Mhz bandwidth) Temperature Coefficient Capacitor Load ± 2% Indefinite (Automatic Recovery) ± 0.5% ± 0.6% 60 mV pk-pk ± 0.02% / °C 220 uF General Specifications Efficiency Switching Frequency Humidity Reliability Calculated MTBF (MIL-HDBK-217F) See Table 330 kHz, typ. 95% rel H > 4.3 Mhrs Physical Specifications Case Material Potting Material Weight Non Conductive Black Plastic (UL94V-0 rated) Epoxy (UL94V-0 rated) ~ 2.0 g, typ.
