ZSPM4023-06

24V/6A Synchronous DC/DC Buck Regulator

Brief Description

Benefits

The ZSPM4023-06 is a constant-frequency, syn-

chronous DC/DC buck regulator featuring adaptive

on-time control architecture. The ZSPM4023-06

operates over a 4.5V to 28V supply range (24V typi-

cal). It has an internal linear regulator that provides a

regulated 5V to power the internal control circuitry.

The ZSPM4023-06 operates at a constant 600kHz

(typical) switching frequency in continuous-

conduction mode and can be used to provide up to

6A of output current. The output voltage is adjust-

able from 5.5V down to 0.8V.



Ultra-light load efficiency – up to 80% at 10mA

Up to 95% efficiency

Feedback reference accuracy as high as ±1%

Features



Rapid-control architecture enables operation with

a high input/output voltage ratio (e.g., V_IN= 28V

and V_OUT= 0.8V) and small output capacitance



Adjustable output voltage from 0.8V to 5.5V

Universally compatible with most output

Under medium to heavy loads, the ZSPM4023-06

provides high efficiency and ultra-fast transient res-

ponse via its rapid-control architecture. Under light

load conditions, it maintains high efficiency and a

superior transient response by transitioning to

variable-frequency, discontinuous mode operation

with its ultra-light-load architecture.

capacitors—stable with zero to high ESR



Power good (PG) output

Foldback current limiting and “hiccup” mode

short-circuit protection



Safe start-up into pre-biased loads

The ZSPM4023-06 offers a full suite of protection

features to ensure protection of the IC during fault

conditions. These include under-voltage lockout to

ensure proper operation under power-sag con-

ditions; thermal shutdown; internal soft-start to

reduce inrush current; foldback current limiting; and

“hiccup” mode short-circuit protection. The

ZSPM4023-06 includes a power good (PG) output to

allow simple sequencing.
