SGM6029

Ultra-Low Quiescent Current,

Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM6029 family is a low voltage, efficient and

miniature synchronous Buck converter with ultra-low

quiescent current. Operating at high switching

frequency (4.0MHz, TYP), miniature inductors and

capacitors can be used to achieve minimal solution size.

The rated load current is from 0.6A to 1A depending on

the input voltage and operating frequency. For high

light-load efficiency, the operating mode can smoothly

and automatically change between power-save mode

and PWM.

● 1.95V to 5.5V Input Voltage Range

● 2.3μA (TYP) Quiescent Current

● Selectable Switching Frequency of 4.0MHz or

1.5MHz

● 0.4V Internal Reference Voltage

● 0.6A to 1A Peak Output Current

● 2% Output Voltage Regulation Accuracy Full

Temperature Range

● Programmable Light Load PSM or FPWM

● Simple Output Voltage Programming with

Integrated R2D Converter

The dual-role VSEL/MODE pin sets the output voltage

to one of the 16 preset values by sensing an external

resistor during startup using an integrated resistor to

digital (R2D) converter. After startup, this pin acts as

MODE input and applying a logic high on it will force the

device in the pulse width modulation (PWM) mode. This

will allow using the same part for a wide range of

voltage rails in different applications and offer a better

output accuracy compared to the conventional external

feedback resistor divider. In the forced-PWM (FPWM),

the device switches at 4.0MHz (A, B and C versions) or

1.5MHz (D and E versions). High switching frequency

reduces the output ripple, but at lighter loads, sacrifices

the efficiency a little bit.

● 16 Selectable + 1 Fixed Output Voltage Levels:

 SGM6029A (4.0MHz): 0.4V to 0.775V

 SGM6029B (4.0MHz): 0.8V to 1.55V

 SGM6029C (4.0MHz): 1.8V to 3.3V

 SGM6029D (1.5MHz): 0.4V to 0.775V

 SGM6029E (1.5MHz): 0.8V to 1.55V

● Enable Pin with Auto Pull-Down during Startup

● Miniature 0201 Optimized Pinout

● Output Discharge Feature (When Disabled)

● 100% Duty Cycle Operation Capability

● Available in a Green WLCSP-0.74×1.09-6B Package
