SGM6010

3A, 2MHz, Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM6010 is a synchronous, buck DC/DC converter

with a range of 3V to 5.5V input voltage. This device is

capable to provide a 3A continuous output current. It

operates with a programmable frequency range of

300kHz to 2MHz. The SGM6010 is highly efficient with

peak efficiency at 95% when in operation. The 100%

duty cycle could make the lowest dropout.

● 3V to 5.5V Input Voltage Range

● Up to 95% High Efficiency

● 120mΩ Low R_DS(ON)Internal Switches

● 300kHz to 2MHz Programmable Frequency

● 3A Output Current

● 0.8V Reference Allows Low Output Voltages

● Shutdown Current: 2μA (MAX)

● 100% Duty Cycle for Lowest Dropout

● Forced Continuous PWM Mode Operation

● No External Power MOSFETs and Schottky Diode

Required

The forced continuous pulse width modulation (PWM)

mode operation could decrease the ripple voltage to

the lowest level and reduce noise and RF interference

as well. No external power MOSFETs and Schottky

diode are required because of the internal synchronous

low on-resistance power switches. The external

compensation can improve the transient response

across the loads and output capacitors.

● Excellent Line and Load Transient Responses

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green TDFN-3×3-10L Package

The SGM6010 is available in a Green TDFN-3×3-10L

package. It is rated over the -40℃ to +85℃ temperature

range.
