TP78Lxx-1 non-isolated dc-dc converter - 1

Wide Input Non-Isolated & Regulated Single Output TP78LXX-1 series switching regulators are ideal replacement for TP78xx linear regulators and LDOs. The efficiency of up to 97% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. They are widely used in industrial control, instrumentation, and electric power applications. The above part number with "L" Suffix are 90” bent pins power converters, for example TP78L1.5-1L. OUTPUT CHARACTERISTICS Conditions 100% full load Vin=min. to max, at full load 10% to 100% load 20MHz bandwidth Parameter Conditions Min Output voltage accuracy Line regulation Load regulation Ripple & Noise Short circuit input power Short circuit protection Thermal shutdown Switching frequency 100% full load 280 Output current limit Output current limit Quiescent current Temperature coefficient Max capacitance load All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified. Internal IC junction 100% full load Vin= min. to max.(at full load) Vout:1.5V~3.3V Vin= min. to max.(at full load) Vout:5V~15V -40"C~+85"C ambient Continuous, automatic recovery 150 Units % mvp-p W C KHz mA mA mA %/C pF COMMON SPECIFICATIONS Parameter Storage humidity Operating temperature Operating case temp Storage temperature Lead temperature Cooling Case material MTBF Weight Conditions Power derating (above 71°C) 1.5mm from case for 10 seconds 25"C(MIL-HDBK-217F)
