description
The TPS5615 family of synchronous-buck regulator controllers provides an accurate supply voltage to DSPs.
The output voltage is internally set by a resistive divider with an accuracy of 1% over the full operating
temperature range. A hysteretic controller with user-selectable hysteresis is used to dramatically reduce
overshoot and undershoot caused by load transients. Propagation delay from the comparator inputs to the
output drivers is less than 250 ns. Overcurrent shutdown and crossover protection for the output drivers
combine to eliminate destructive faults in the output FETs. PWRGD monitors the output voltage and pulls the
open-collector output low when the output drops below 93% of the nominal output voltage. An overvoltage circuit
disables the output drivers if the output voltage rises 15% above the nominal value. The inhibit pin can be used
to control power sequencing. Inhibit and undervoltage lockout assures that the 12-V supply voltage and system
supply voltage (5 V or 3.3 V) are within proper operating limits before the controller starts. The output driver
circuits include 2-A drivers with internal 8-V gate-voltage regulators that can easily provide sufficient power for
today’s high-powered DSPs. The high-side driver can be configured either as a ground-referenced driver or as
a floating bootstrap driver. The TPS5615 family is available in a 28-pin TSSOP PowerPad
package. It operates
over a junction temperature range of 0
°C to 125°C.
