Datasheet Summary
1/2/3/4-Phase PWM Controller with SVID for VR12.5
General Description
Features
The uP1651 is a VR12.5 pliant 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 ply 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.
