GENERAL DESCRIPTION
The ADP1053, based on a voltage mode PWM architecture, is
a flexible, application dedicated digital controller designed for
isolated and nonisolated dc-to-dc power supply applications.
The ADP1053 enables highly efficient power supply design and
facilitates the introduction of intelligent power management
techniques to improve energy efficiency at a system level.
The ADP1053 provides control, monitoring, and protection
of up to three independent channel outputs. The eight flexible
PWM outputs can be configured as three independent channels:
two regulated channels with feedback control plus one additional
unregulated channel with a fixed duty cycle. The frequency of
these three channels can be programmed individually from
50 kHz to 625 kHz; all channels can be synchronized internally
or to an external signal.
All eight PWM outputs can also be assigned to enable a single-
channel solution, which may be required in high power, high
efficiency applications.
Features include differential voltage sensing, fast current sensing,
flexible start-up sequencing and tracking, and synchronization
between devices to reduce low frequency system noise. Protection
and monitoring features include overcurrent protection (OCP),
undervoltage protection (UVP), overvoltage protection (OVP),
and overtemperature protection (OTP).
