A6985F

38 V 500 mA synchronous step-down switching regulator

with 30 µA quiescent current

Datasheet - production data

Description

The A6985F automotive grade device is a step-

down monolithic switching regulator able to

deliver up to 0.5 A DC. The output voltage

adjustability ranges from 0.85V to VIN. The 100%

duty cycle capability and the wide input voltage

HTSSOP16 (R_TH= 40 °C/W)

range meet the cold crank and load dump

specifications for automotive systems. The “Low

Consumption Mode” (LCM) is designed for

applications active during car parking, so it

maximizes the efficiency at light-load with

Features

 AECQ100 qualification

controlled output voltage ripple. The “Low Noise

Mode” (LNM) makes the switching frequency

constant and minimizes the output voltage ripple

overload current range, meeting the low noise

application specification like car audio. The output

voltage supervisor manages the reset phase for

any digital load (µC, FPGA). The RST open

collector output can also implement output

voltage sequencing during the power-up phase.

The synchronous rectification, designed for high

efficiency at medium - heavy load, and the high

switching frequency capability make the size of

the application compact. Pulse by pulse current

sensing on both power elements implements an

effective constant current protection.

 0.5 A DC output current

 4 V to 38 V operating input voltage

 Low consumption mode or low noise mode

 30 µA I at light-load (LCM V

= 3.3 V)

OUT

 8 µA I

Q-SHTDWN

 Fixed output voltage (3.3 V and 5 V) or

adjustable from 0.85 V to V

 Adjustable f

(250 kHz - 2 MHz)

 Embedded output voltage supervisor

 Synchronization

 Adjustable soft-start time

 Internal current limiting

 Overvoltage protection

 Output voltage sequencing

 Peak current mode architecture

 R

= 360 m, R

= 150 m

DSON HS

 Thermal shutdown

Applications

 Designed for automotive systems

 Battery powered applications

 Car body applications (LCM)

 Car audio and low noise applications (LNM)
