Product Overview

The TPS40140RHHT is a multifunctional synchronous Buck Controller can be configured to provide either a single-output 2-phase power supply or a power supply that supports two independent outputs. Several TPS40140 controllers can be stacked up to a 16-phase single output power supply. Alternatively, several controllers providing multiple independent outputs can be synchronized in an interleaving pattern for improved input ripple current. The TPS40140 can convert from a 15 input to a 0.7V output at 1MHz. Each phase operates at a switching frequency of up to 1MHz. The two phases in one device operate 180° out-of-phase.
  • Dual-output or 2-phase interleaved operation
  • Stackable to 16 phases
  • Supports pre-biased outputs
  • 0.5% internally trimmed 0.7V reference
  • 10µA shutdown current
  • Current mode control with forced current
  • Power sharing from different input voltage rails
  • True remote sensing differential amplifier
  • Programmable input undervoltage lockout (UVLO)
  • Resistive or inductor DCR current sensing
  • Green product and no Sb/Br
