LM2731 0.6/1.6-MHz Boost Converters With 22-V Internal FET Switch in SOT-23

1 Features

3 Description

The LM2731 switching regulators are current-mode

boost converters operating at fixed frequencies of 1.6

MHz (X option) and 600 kHz (Y option).

•

22-V DMOS FET Switch

•

1.6-MHz (X Option), 0.6-MHz (Y Option) Switching

Frequency

The use of SOT-23 package, made possible by the

minimal power loss of the internal 1.8-A switch, and

use of small inductors and capacitors result in the

highest power density of the industry. The 22-V

internal switch makes these solutions perfect for

boosting to voltages up to 20 V.

•

Low R_DS(ON) DMOS FET

Switch Current Up to 1.8 A

Wide Input Voltage Range (2.7 V to 14 V)

Low Shutdown Current (<1 µA)

5-Lead SOT-23 Package

These parts have a logic-level shutdown pin that can

reduce quiescent current and extend battery life.

Uses Tiny Capacitors and Inductors

Cycle-by-Cycle Current Limiting

Internally Compensated

Protection is provided through cycle-by-cycle current

limiting and thermal shutdown. Internal compensation

simplifies design and reduces component count.
