ZSPM2000 Datasheet

January 27, 2016

The DPWM supports switching frequencies up to 1MHz with a resolution of approximately 163ps. The minimum

on-time and the maximum off-time of the modulation signal can be configured so that the ZSPM2000 can match

the external power MOSFETs optimally. The functionality of the synchronous MOSFET driver is described in

section 6.

3.3.5.

Power Sequencing and the CONTROL Pin

The ZSPM2000 supports power sequencing features including ramp up/down and delays programmable via the

Pink Power Designer™ GUI. The typical sequence of events is shown in Figure 3.2 and follows the PMBus™

standard. The individual values can be configured using the appropriate configuration setting. Three different

configuration options are supported to turn on the output of the ZSPM2000. The device can be configured to turn

on immediately after POR, on an OPERATION_ON command, or on an edge on the CONTROL pin.
