The SGM61031SH and SGM61031SL are efficient high frequency synchronous Buck converter with an input voltage range of 2.5V to 5.5V and a wide output current range that is optimized for compact solutions. It operates in PWM mode at heavy loads and automatically enters power-save mode (PSM) at light loads to maintain its high efficiency.
With its adaptive hysteresis and pseudo-constant on-time control (AHP-COT) architecture, the load transient performance is excellent and the output voltage regulation accuracy is achieved.
The SGM61031SH and SGM61031SL guarantee robustness by full protection function including input under-voltage lockout, cycle-by-cycle current limit and over-temperature protection. SGM61031SH integrates hiccup output under-voltage protection. SGM61031SL integrates latch-off output over-voltage protection and hiccup output under-voltage protection.
The SGM61031SH and SGM61031SL are available in a Green TDFN-2×2-8AL package.
