For assistance or to order, call (800) 531-5782 Revised 3/1/99 48V PT4100 Series Power Trends’ PT4100 series of Isolated 48V DC-DC Converters advance the state-ofthe-art for board-mounted converters by employing high switching frequencies greater than 650 KHz and planar magnetics and surface-mount construction. They feature the industry’s smallest footprint, a power density of 15 Watts/in3, and operate at 82% efficiency. They are designed for Telecom, Industrial, Computer, Medical, and other distributed power applications requiring input-to-output isolation and an industrial temperature range. • -40°C to +85°C Operating Temperature Range • 1500 VDC Isolation • Power Density 15 Watts/in3 • Wide Input Voltage Range 36V to 75V • 82% Efficiency • Small Footprint • Fast Transient Response • UL Approved Specifications Standard Application PT4100 SERIES Characteristics (Ta=25°C unless noted) Symbols Conditions Output Current Io Over Vin range Current Limit Icl Vin = 36V On/Off Standby Current Iin standby Short Circuit Current Inrush Current On/Off Min Typ Max Units Vo = 3.3V Vo = 5V Vo = 12V Vo = 15V 0 0 0 0 — — — — 4.0 3.0 1.25 1.0 A A A A Vo = 5V Vo = 12V Vo = 15V — — — 4.00 1.75 1.4 — — — A A A Vin = 48V, Pin 1 = -Vin — 7 10 mA Pin Isc Vin = 48V — — — 5.5 3.5 2.0 — — — A A A 1 Remote ON/OFF Iir tir Vin = 48V @ max Io On start-up — — 0.6 1.0 1.0 5.0 A mSec 2 -Vin 3 +Vin Input Voltage Range Vin Io = 0.1 to max Io 36.0 48.0 75.0 V 4 ∆Vo -Vout Output Voltage Tolerance Over Vin Range TA= -40°C to +85°C — ±1.0 ±2.0 %Vo 5 +Vout dB 6 Do not connect 1 +Vin Vo = 5V Vo = 12V Vo = 15V Ripple Rejection RR Over Vin range @ 120 Hz Line Regulation Regline Over Vin range @ max Io — ±0.2 ±1.0 %Vo Load Regulation Regload 10% to 100% of Io max — ±0.4 ±1.0 %Vo Vo Ripple/Noise Vn Vin=48V, Io=3.0A, Vo=5V Vin=48V, Io=1.25A, Vo=12V Vin=48V, Io=1.0A, Vo=15V — — — 75 120 100 100 150 200 mVpp mVpp mVpp Transient Response ttr 50% load change Vo over/undershoot — — 100 3.0 200 5.0 µSec %Vo Efficiency η Vin=48V, Io=3.0A, Vo=5V Vin=48V, Io=1.25A, Vo=12V Vin=48V, Io=1A, Vo=15V — — — 80 81 82 — — — % % % Switching Frequency ƒo Over Vin and Io, Vo=5V Vo=12V/15V 800 600 850 650 900 700 kHz kHz Recommended Operating Temperature Range Ta Vin = 48V @ max Io Free air convection, (40-60LFM) 200 LFM PT4110 -40 0 — — +85* +70 °C °C Thermal Resistance θja Free Air Convection, (40-60LFM) — 14 — °C/W Case Temperature Tc @ Thermal shutdown — — 100 °C Storage Temperature Ts — -40 — 110 °C Mechanical Shock — Per Mil-STD-202F, Method 213B, 6mS, Half-sine, mounted to a PCB — 50 — G’s Mechanical Vibration — Per Mil-STD-202F, Method 204D, 10-500Hz, Soldered in a PCB — 10 — G’s Weight — — — 28 — grams Isolation Capacitance Resistance — — — — — — 1500 — 10 — 1100 — — — — V pF MΩ Flammability — Remote On/Off On Off * See thermal derating curves 70 Application Notes Mechanical Outline Product Selector Guide 48V 15 WATT ISOLATED DC-DC CONVERTER — 60 — -Vin 3 2 PT4100 5 +Vout 4 -Vout Pin-Out Information Function Ordering Information Through-Hole PT4101A = 5 Volts PT4102A = 12 Volts PT4103A = 15 Volts PT4110A = 3.3 Volts PT4117A = 5.2 Volts Surface Mount PT4101C = 5 Volts PT4102C = 12 Volts PT4103C = 15 Volts PT4110C = 3.3 Volts PT4117C = 5.2 Volts (For dimensions and PC board layout, see Package Style 700.)
