DESCRIPTION

The LM20146 is a full featured adjustable frequency

synchronous buck regulator capable of delivering up

to 6A of continuous output current. The current mode

control loop can be compensated to be stable with

virtually any type of output capacitor. For most cases,

compensating the device only requires two external

components, providing maximum flexibility and ease

of use. The device is optimized to work over the input

voltage range of 2.95V to 5.5V making it suitable for

a wide variety of low voltage systems.

The device features internal over voltage protection

(OVP) and over current protection (OCP) circuits for

increased system reliability. A precision enable pin

and integrated UVLO allows the turn-on of the device

to be tightly controlled and sequenced. Start-up

inrush currents are limited by both an internally fixed

and externally adjustable Soft-Start circuit. Fault

detection and supply sequencing are possible with

the integrated power good circuit.

The LM20146 is designed to work well in multi-rail

power supply architectures. The output voltage of the

device can be configured to track a higher voltage rail

using the SS/TRK pin. If the output of the LM20146 is

pre-biased at startup it will not pull the ouput low.

The frequency of this device can be adjusted from

250 kHz to 750 kHz by connecting an external

resistor from the RT pin to ground.

The LM20146 is offered in a 16-pin HTSSOP

package with an exposed pad that can be soldered to

the PCB, eliminating the need for bulky heatsinks.
