SGM61720

High Efficiency, 2.5A, 60V Input

Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM61720 is a constant on-time control (COT)

synchronous Buck converter with a wide input voltage

range from 6V to 60V. The output voltage is adjustable

up to 24V using the internal reference voltage. This

device has 2.5A output current capability and operates

at an almost fixed quasi-constant frequency (depending

on V_OUTsetting). With light load, the inductor current

reaches zero in each cycle (DCM operation) and the

device shifts into power-save mode in which frequency

drops and becomes load dependent to maintain high

efficiency.

● Integrated 100mΩ/75mΩ Power MOSFETs

● Wide 6V to 60V Input Voltage Range

● 2.5A/5V Output Current Capability

● Constant On-Time (COT) Control

● Power-Save Mode and PWM Mode

● 1ms Internal Soft-Start for Inrush Current Limit

● Up to 24V Adjustable Output Voltage

● Pre-biased Startup

● -40℃ to +125℃ Operating Junction

Temperature Range

● Available in a Green SOIC-8 (Exposed Pad)

Package

The SGM61720 offers a broad set of features including

input under-voltage lockout, internal soft-start, short-

circuit protection, current limiting and thermal shutdown.

APPLICATIONS

Non-Isolated Telecommunication Buck Regulators

Secondary High Voltage Post-Regulators

Automotive Systems

Using COT architecture, the device is capable of high

step-down conversion ratios while offering excellent

transient response with no need for loop compensation.

Mobile Base Stations

The SGM61720 is available in a Green SOIC-8 (Exposed

Pad) package.
