11 / 25 page TPS5615, TPS5618, TPS5625, TPS5633 SYNCHRONOUS-BUCK HYSTERETIC REGULATOR CONTROLLER SLVS177A – SEPTEMBER 1998 – REVISED NOVEMBER 1998 11 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 electrical characteristics over recommended operating virtual junction temperature range, VCC = 12 V, IDRV = 0 A (unless otherwise noted) (continued) bias regulator PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Output voltage 11.4 V ≤ VCC ≤ 12.6 V, See Note 3 6 V NOTE 3: The bias regulator is designed to provide a quiet bias supply for the TPS56xx controller. External loads should not be driven by the bias regulator. output drivers PARAMETER (see Note 4) TEST CONDITIONS MIN TYP MAX UNIT High-side sink Duty cycle < 2%, tpw < 100 µs, TJ = 125°C, VBOOT VBOOTLO 65 V 2 Peak output current High-side source VBOOT – VBOOTLO = 6.5 V, VHIGHDR = 1.5 V (SRC) or 5 V (sink), See Note 2 2 A Peak output current Low-side sink Duty cycle < 2%, tpw < 100 µs, TJ = 125°C, VDRV 65 V VLOWDR 1 5 V (SRC) or 5 V 2 A Low-side source VDRV = 6.5 V, VLOWDR = 1.5 V (SRC) or 5 V (sink), See Note 2 2 High-side sink TJ = 125°C, VBOOT – VBOOTLO = 6.5 V, 3 Output resistance High-side source J , BOOT BOOTLO , VHIGHDR = 1.5 V (SRC) or 5 V (sink) 45 Ω Output resistance Low-side sink TJ = 125°C, VDRV = 6.5 V, 5.7 Ω Low-side source J DRV VLOWDR = 1.5 V (SRC) or 5 V (sink) 45 NOTES: 2. Ensured by design, not tested. 4. The pull up/down circuits of the drivers are bipolar and MOSFET transistors in parallel. The peak output current rating is the combined current from the bipolar and MOSFET transistors. The output resistance is the RDS(ON) of the MOSFET transistor when the voltage on the driver output is less than the saturation voltage of the bipolar transistor. supply current PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VCC supply voltage range 11.4 12 13 V VINHIBIT = 5 V, VBOOTLO = 0 V, VCC > 10.75 V at startup, See Note 2 3 10 VCC quiescent current VINHIBIT = 5 V, VBOOTLO = 0 V, CLOWDR = 50 pF, VCC > 10.75 V at startup, CHIGHDR = 50 pF, fswx = 200 kHz 5 mA VINHIBIT = 0 V or VCC < 9.25 V at startup, VBOOT = 13 V, VBOOTLO = 0 V 10 µA High-side drive regulator quiescent current VINHIBIT = 5 V, VBOOT = 13 V, CHIGHDR = 50 pF, VCC > 10.75 V at startup, VBOOTLO = 0 V, fswx = 200 kHz 2 mA NOTE 2: Ensured by design, not tested. |
