PTC-06211 SERIES DC/DC CONVERTERS MINIATURE, HIGH DENSITY, HIGH EFFICIENCY SINGLE OUTPUT (UP TO 200W) Applications Military (Airborne, ground-fix, shipboard), Ruggedized, Telecom, Industrial Special Features • Miniature size • High efficiency • Wide input range • Input / Output isolation • Remote sense • External On/Off Inhibit • Zero Voltage Switching Technology • Fixed switching frequency (250 KHz) • External synchronization capability • EMI/RFI filters included • Indefinite short circuit protection with auto-recovery • Over-voltage shutdown with auto-recovery • Over temperature shutdown with auto-recovery DC Input: DC Input range: 18 to 48 VDC, per MIL-STD-704E No damage for: MIL-STD-1275A (100V for 50mSec) MIL-STD-704A (80V for 0.1Sec) DC Output: Output range – 1.5 to 28V Output current – max 40A Isolation 200V between Input and Output 200V between Input and Case 100V between Output and Case Line/Load regulation: Less than 1% (no load to full load, –55°C to +85°C) Efficiency : Typical 90-92% (full load, room temperature) Ripple and Noise: Less than 50mVp-p, typical (max. 1%) without external capacitance. When connected to system capacitance ripple drops significantly Load Transient Overshoot and Undershoot Output resistance at load change of 50%100% is 30-200mOhm (depending on output voltage). Output back to steady stated within 300-500µSec Turn on Transient Voltage overshoot at during power on is less than 3% nominal voltage Output • Electronic over voltage protection – Internal control protects unit (no damage) 10% above nominal voltage • Passive tranzorb on outputs – 20% above nominal voltage • Current limiting – Continuous protection (10-30% above maximum current) for unlimited time (Hiccup) General • Over temperature protection: Shutdown at base plate temperature of +105°C (±5°C) Automatic recovery at base plate temperature lower than +95°C (±5°C) Electrical Specifications Protections* Input • Inrush Current Limiter – peak value of 5 x Iin for less than 50µSec • Under voltage protection – unit protects itself (no damage) below 16.5Vdc • Over voltage protection – unit protects itself (no damage) above 52Vdc * Thresholds and protections can be modified / removed – please consult factory.

FUNCTIONS AND SIGNALS INHIBIT signal The INHIBIT signal is used to turn the power supply ON and OFF. TTL “1”or OPEN – will turn on the power supply. (For normal operation leave the signal not connected.) TTL “0” – will turn off the power supply. SYN IN signal The SYNC IN signal is used to allow the power supply frequency to sync with the system frequency. The system frequency should be 250KHz ± 10KHz. When not connected the power supply will work at 250KHz SIGNAL RTN The INPUT SIGNAL RTN is referred to the input. This is used as grounding for SYNC IN SYNC OUT and INHIBIT signals. SENSE The SENSE...
