This data is considered typical data for the Converter. Note B: SOA curves represent the conditions at which internal components are at or below the manufacturer’s maximum operating temperatures PT6938 Performance Specifications (Unless otherwise stated, Ta =25°C, Vin =5V, C1 =330µF, C2 =330µF, Io1 =Io1typ, and Io2 =Io2typ) PT6938 (3.3V/1.2V) Characteristic Symbol Conditions Min Typ Max Units Output Current Io1 Ta =25°C, natural convection Vo1 (3.3V) 0.1 (i) 7 (ii) 8.6 (iii) A Io2 Vo2 (1.2V) 0 1.6 (ii) 1.6 (iii) Io1 Ta =60°C, 200LFM airflow Vo1 (3.3V) 0.1 (i) 7 (ii) 8.6 (iii) A Io2 Vo2 (1.2V) 0 1.6 (ii) 1.6 (iii) Input Voltage Range Vin OverIoRange 4.5 — 5.5 VDC Set Point Voltage Tolerance Vo tol Vo1 — ±16 ±50 mV Vo2 — ±6 ±18 Temperature Variation Regtemp –40° >Ta > +85°C — ±0.5 — %Vo Line Regulation Regline Over Vin range Vo1 — ±5 ±10 mV Vo2 —±2±5 Load Regulation Regload Over Io range Vo1 — ±5 ±10 mV Vo2 — ±5 ±10 Total Output Voltage Variation ∆Votot Includes set-point, line, load, Vo1 —±29 — mV –40° >Ta > +85°C Vo2 — ±19 — Efficiency η —79 — % Vo Ripple (pk-pk) Vr 20MHz bandwidth Vo1 —35 — mVpp Vo2 —35 — TransientResponse ttr 1A/µs load step, 50% to 100% Iotyp — 60 — µs ∆Vtr Vo over/undershoot Vo1 — ±60 — mV Vo2 — ±60 — Notes: (i) Io1(min) current of 0.1A can be divided between both outputs, Vo1 or Vo2. The module will operate at no load with reduced specifications. (ii) The typical current is that which can be drawn simultaneously from both outputs under the stated operating conditions. (iii) The sum of Io1 and Io2 must be less than Io1max, and Io2 must be less than Io2max. 60 65 70 75 80 85 01234 567 Io1 (A) [ Io2 fixed at Io2(typ) ] 5.0V VIN 0 2 4 6 8 10 01234 567 Io1 (A) [ Io2 fixed at Io2(typ) ] 5.0V 20 30 40 50 60 70 80 90 01234 567 Io1 (A) [ Io2 fixed at Io2(typ) ] 200LFM 120LFM 60LFM Nat conv Airflow |
