Use either a low ESR tantalum, Os-con, or ceramic capacitor. (ii) During reflow of SMD package version do not elevate peak temperature of the module, pins or internal components above the stated maximum. 6-A, 5-V Input Non-Isolated Wide-Output Adjust Power Module SLTS201C – MAY 2003 – REVISED DECEMBER 2003 PTH05000W —5-V Input Electrical Specifications Unless otherwise stated, Ta =25 °C, Vin =5 V, Vo =3.3 V, Cin =330 µF, Cout =0 µF, and Io =Io(max) PTH05000W Characteristics Symbols Conditions Min Typ Max Units Output Current Io 0.9 V ≤ Vo ≤3.6 V, Ta =25 °C, natural convection 0 — 6 (1) A Ta =60 °C, 200LFM 0 — 5.25 (1) Input Voltage Range Vin Over Io range 4.5 — 5.5 V Set-Point Voltage Tolerance Vo tol — — ±2 (2) %Vo Temperature Variation ∆Regtemp –40 °C <Ta < +85 °C — ±0.5 — %Vo Line Regulation ∆Regline Over Vin range — ±5 — mV Load Regulation ∆Regload Over Io range — ±5 — mV Total Output Variation ∆Regtot Includes set-point, line, load, — — ±3 (2) %Vo –40 °C ≤ Ta ≤ +85 °C Efficiency η Vin =5 V, Io =4 A RSET = 475 Ω Vo = 3.3 V — 92 — RSET = 2.32 kΩ Vo = 2.5 V — 90 — RSET = 4.87 kΩ Vo = 2.0 V — 88 — RSET = 6.65 kΩ Vo = 1.8 V — 87 — % RSET = 11.5 kΩ Vo = 1.5 V — 84 — RSET = 26.1 kΩ Vo = 1.2 V — 82 — RSET = 84.5 kΩ Vo = 1.0 V — 79 — Vo Ripple (pk-pk)Vr 20 MHz bandwidth Vo ≥3.3 V — 30 — mVpp Vo ≤2.5 V — 25 — Transient Response 1 A/µs load step, 50 to 100 % Iomax, Vo =1.8 V, Cout =100 µF ttr Recovery time — 70 — µSec ∆Vtr Vo over/undershoot — 100 — mV Current Limit Ilim ∆Vo = –50 mV — 13 — A Under-Voltage Lockout UVLO Vin increasing — 3.8 4.3 V Vin decreasing 3.4 3.5 — Inhibit Control (pin 3)Referenced to GND Input High Voltage VIH Vin –0.5 — Open (3) V Input Low Voltage VIL –0.2 — 0.8 Input Low Current IIL Pin 3 to GND — –10 — µA Standby Input Current Iin standby pins 1 & 3 connected — 1 — mA Switching Frequency ƒs Over Vin and Io ranges — 700 — kHz External Input Capacitance Cin 330 (4) ——µF External Output Capacitance Cout Capacitance value non-ceramic 0 100 (5) 1,000 (6) µF ceramic 0 — 300 Equiv. series resistance (non-ceramic)4 (7) ——m Ω Reliability MTBF Per Bellcore TR-332 28 ——106 Hrs 50 % stress, Ta =40 °C, ground benign Notes: (1) See SOA curves or consult factory for appropriate derating. (2) The set-point voltage tolerance is affected by the tolerance and stability ofRSET. The stated limit is unconditionally met if RSET has a tolerance of 1 % with 100 ppm/°C or better temperature stability. (3) The Inhibit control (pin 3) has an internal pull-up to Vin, and if left open-circuit the module will operate when input power is applied. A small low- leakage (<100 nA) MOSFET is recommended to control this input. See application notes for more information. (4) The regulator requires a minimum of 330 µF input capacitor with a minimum 300 mArms ripple current rating. For further information, consult the related application note on Capacitor Recommendations. (5) An external output capacitor is not required for basic operation. Adding 100 µF of distributed capacitance at the load will improve the transient response. (6) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance. (7) This is the typical ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 m Ω as the minimum when using max-ESR values to calculate. |
