3 Description

– Au bondwire and NiPdAu lead finish

– Enhanced mold compound for low outgassing

– One fabrication, assembly and test site

– Extended product life cycle

– Extended product change notification

– Product traceability

Wide voltage conversion range:

– t_ON-MIN= 60 ns (typical)

– t_OFF-MIN= 70 ns (typical)

Low MOSFET ON-resistance:

– R_{DS_ON_HS}= 53 mΩ (typical)

– R_{DS_ON_LS}= 31 mΩ (typical)

Adjustable frequency range: 350 kHz to 2.2 MHz

Synchronizable to external clock

Internal compensation

The TPS7H4010-SEP is an easy-to-use synchronous

step-down DC/DC converter capable of driving up to 6

A of load current from a supply voltage ranging from

3.5 V to 32 V. The TPS7H4010-SEP provides

exceptional efficiency and output accuracy in a very

small solution size. Peak current-mode control is

employed. Additional features such as adjustable

switching frequency, synchronization to an external

clock, FPWM option, power-good flag, precision

enable, adjustable soft start, and tracking provide both

flexible and easy-to-use solutions for a wide range of

applications. Automatic frequency foldback at light

load and optional external bias improve efficiency

over the entire load range. The device requires few

external components and has a pinout designed for

simple PCB layout with optimal EMI and thermal

performance. Protection features include thermal

shutdown, input undervoltage lockout, cycle-by-cycle

current limiting, and hiccup short-circuit protection.
