ST1S06

Synchronous rectification with inhibit, 1.5A, 1.5 MHz fixed or

adjustable, step-down switching regulator in DFN6 3x3

General features

■

Step-down current mode PWM (1.5MHz) DC-

DC converter

2% DC output voltage tolerance

Synchronous rectification

Inhibit function

Internal soft start

Typical efficiency:> 90%

1.5A Output current capability

Not switching quiescent current: max 1.5mA

over temperature range

ON typ150m

Ω

Uses tiny capacitors and inductors

Operative junction temp. -30°C to 125°C

Available in DFN6 3x3 exposed pad

high current linear solution when the power

dissipation may cause an high heating of the

application environment. It provides up to 1.5A

over an input voltage range of 2.7V to 6V. An high

switching frequency (1.5MHz) allows the use of

tiny surface-mount components: as well as the

resistor divider to set the output voltage value,

only an inductor and two capacitors are required.

Besides, a low output ripple is guaranteed by the

current mode PWM topology and by the use of low

E.S.R. SMD ceramic capacitors. The device is

thermal protected and current limited to prevent

damages due to accidental short circuit. The

ST1S06 is available in DFN6 3x3 package.

DFN6 (3x3mm)

Description

The ST1S06 is a step down DC-DC converter

optimized for powering low-voltage digital core in

HDD applications and, generally, to replace the
