TPS62660, TPS62665 SLVS871C – FEBRUARY 2010 – REVISED JULY 2011 www.ti.com DETAILED DESCRIPTION OPERATION The TPS6266x is a synchronous step-down converter typically operates at a regulated 6-MHz frequency pulse width modulation (PWM) at moderate to heavy load currents. At light load currents, the TPS6266x converter operates in power-save mode with pulse frequency modulation (PFM).

TPS62660, TPS62665 SLVS871C – FEBRUARY 2010 – REVISED JULY 2011 www.ti.com OUTPUT CAPACITOR DISCHARGE The TPS6266x device can actively discharge the output capacitor when it turns off. The integrated discharge resistor has a typical resistance of 15 Ω. The required time to discharge the output capacitor at the output node depends on load current and the output capacitance value. UNDERVOLTAGE LOCKOUT The undervoltage lockout circuit prevents the device from misoperation at low input voltages.

TPS62660, TPS62665 SLVS871C – FEBRUARY 2010 – REVISED JULY 2011 www.ti.com APPLICATION INFORMATION INDUCTOR SELECTION The TPS62660 series of step-down converters have been optimized to operate with an effective inductance value in the range of 0.3μH to 1.3μH and with output capacitors in the range of 4.7μF to 10μF. The internal compensation is optimized to operate with an output filter of L = 0.47μH and CO = 4.7μF.
PAGE 20
TPS62660, TPS62665 SLVS871C – FEBRUARY 2010 – REVISED JULY 2011 www.ti.com OUTPUT CAPACITOR SELECTION The advanced fast-response voltage mode control scheme of the TPS6266x allows the use of tiny ceramic capacitors. Ceramic capacitors with low ESR values have the lowest output voltage ripple and are recommended. For best performance, the device should be operated with a minimum effective output capacitance of 1.6μF. The output capacitor requires either an X7R or X5R dielectric.

TPS62660, TPS62665 SLVS871C – FEBRUARY 2010 – REVISED JULY 2011 www.ti.com LAYOUT CONSIDERATIONS As for all switching power supplies, the layout is an important step in the design. High-speed operation of the TPS6266x devices demand careful attention to PCB layout. Care must be taken in board layout to get the specified performance. If the layout is not carefully done, the regulator could show poor line and/or load regulation, stability and switching frequency issues as well as EMI problems.
