SGM6033

4.6MHz, 1A Synchronous Buck Regulator

GENERAL DESCRIPTION

FEATURES

The SGM6033 is a high-efficient Buck switching

voltage regulator, supporting up to 1A output current

and adjustable output voltage. This device is

capable for an input voltage supply range of 2.5V to

5.5V. The 4.6MHz PWM mode frequency operation

allows the use of a 470nH output inductor and a

4.7μF output capacitor.

● 2.5V to 5.5V Input Voltage Range

● 1A Output Current Capability

● 26μA Typical Quiescent Current

● 4.6MHz Fixed Frequency Operation

● Excellent Efficiency and Load Transient Response

● 0.8V Reference Voltage

● Low Ripple Light-Load PFM Mode

● Internal Soft-Start

● Input Under-Voltage Lockout (UVLO)

● Thermal Shutdown

● Overload Protection

● Output Discharge

● Available in Green TDFN-2×2-6L and

WLCSP-1.21×0.81-6B Packages

● -40℃ to +125℃ Operating Temperature Range

The SGM6033 operates in power-save mode under

moderate and light load conditions through pulse

frequency modulation (PFM). The 26μA typical

quiescent current and the power-save mode can

further improve the system efficiency which can

reach a maximum of 90%. The SGM6033 has

excellent load transient response capability. The

SGM6033 also includes features of internal

soft-start, input under-voltage lockout, thermal

shutdown and overload protection.

The SGM6033 is available in Green TDFN-2×2-6L and

WLCSP-1.21×0.81-6B packages. It operates over an

ambient temperature range of -40℃ to +125℃.
