uP1651 - 1/2/3/4-Phase PWM Controller

Features

  • The uP1651 is a VR12.5 compliant PWM controller that surpports 1/2/3/4-phase operation. This device integrates 3 MOSFET gate drivers with embedded bootstrap diode, and provides 1 PWM output to support 4 phase operation. To comply with VR12.5 specification, the uP1651 accurately reports output current and VR temperature. The uP1651 provides programmable 1/2/3/4 phase operation. uP1651 integrates 3 bootstrapped drivers that support 12V + 12V driving capability. 1/2/3/4 phase operation is enabled.

uP1651 1/2/3/4-Phase PWM Controller with SVID for VR12.5 General Description Features The uP1651 is a VR12.5 compliant PWM controller that surpports 1/2/3/4-phase operation. This device integrates 3 MOSFET gate drivers with embedded bootstrap diode, and provides 1 PWM output to support 4 phase operation. To comply with VR12.5 specification, the uP1651 accurately reports output current and VR temperature. The uP1651 provides programmable 1/2/3/4 phase operation. uP1651 integrates 3 bootstrapped drivers that support 12V + 12V driving capability. 1/2/3/4 phase operation is enabled by a logic level ISENx output, achieving optimal balance between cost and flexibility. The uP1651 supports automatic phase adding/dropping that is activated by PSI command from SVID or H/W PSI setting.
