TPS40140RHHT Datasheet PDF - TI

●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. In a multiple-device stackable configuration, the phase shift of the slaves, relative to a master, is programmable.

● 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

●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
