PS1500
Ultra-Low Quiescent Synchronous Step-Down Buck Controller
 |
General Description
PS1500 is a cost-effective, half-bridge gate driver with embedded bootstrap switch. Aimed for power supply solution of each computer field. The device
achieves ultra-low quiescent when system enters sleep mode and low power consumption with external pin selectable FCCM/SDEM, respectively which could be beneficial for long battery life in system stand-by mode and avoid audio noise.
V2COT-based architecture with current injection supports MLCCs output capacitors application without external compensation network. The PS1500 operates with supply input voltage range from 3V to 28V and supports output voltages of 0.7V to5V. The PS1500 is available in a 10-pin 3x3 (mm) QFN package and is specified from -40°C to +85°C ambient temperature range. |
