4. PowerPSoC Functional Overview
The PowerPSoC family incorporates programmable
system-on-chip technology with the best in class power
electronics controllers and switching devices to create easy to
use power-system-on-chip solutions for lighting applications.
All PowerPSoC family devices are designed to replace
traditional MCUs, system ICs, and the numerous discrete
components that surround them. PowerPSoC devices feature
high performance power electronics including 1 ampere 2 MHz
power FETs, hysteretic controllers, current sense amplifiers, and
PrISM/PWM modulators to create a complete power electronics
solution for LED power management. Configurable power,
analog, digital, and interconnect circuitry enables a high level of
integration in a host of industrial, commercial, and consumer
LED lighting applications.
This architecture integrates programmable analog and digital
blocks to enable you to create customized peripheral
configurations that match the requirements of each individual
application. Additionally, the device includes a 24 MHz CPU,
Flash program memory, SRAM data memory, and configurable
I/O in a range of convenient pinouts and packages.
The PowerPSoC architecture, as illustrated in the block
diagrams, consists of five main areas: PSoC core, digital system,
analog system, system resources, and power peripherals, which
include power FETs, hysteretic controllers, current sense
amplifiers, and PrISM/PWM modulators. Configurable global
busing combines all of the device resources into a complete
custom system. The PowerPSoC family of devices have 10-port
I/Os that connect to the global digital and analog interconnects,
providing access to eight digital blocks and six analog blocks.
5. Power Peripherals
PowerPSoC is designed to operate at voltages from 7 V to 32 V,
drive up to 1 ampere of current using internal MOSFET switches,
and over 1 ampere with external MOSFETs.
This family of devices (CY8CLED0xD/G0y) combines up to four
independent channels of constant current drivers. These drivers
feature hysteretic controllers with the Programmable
System-on-Chip (PSoC) that contains an 8-bit microcontroller,
configurable digital and analog peripherals, and embedded flash
memory.
The CY8CLED0xD/G0y is the first product in the PowerPSoC
family to integrate power peripherals to add further integration for
your power electronics applications.The PowerPSoC family of
intelligent power controller ICs are used in lighting applications
that need traditional MCUs and discrete power electronics
support. The power peripherals of the CY8CLED0xD/G0y
include up to four 32 volt power MOSFETs with current ratings
up to 1 ampere each. It also integrates gate drivers that enable
applications to drive external MOSFETs for higher current and
voltage capabilities. The controller is a programmable threshold
hysteretic controller, with user-selectable feedback paths that
uses the IC in current mode floating load buck, floating load
buck-boost, and boost configurations.
5.1 Hysteretic Controllers
The PowerPSoC contains four hysteretic controllers. There is
one hysteretic controller for each channel of the device.
The hysteretic controllers provide cycle by cycle switch control
with fast transient response, which simplifies system design by
requiring no external compensation. The hysteretic controllers
include the following key features:
■ Four independent channels
■ DAC configurable thresholds
■ Wide switching frequency range from 20 kHz to 2 MHz
■ Programmable minimum on and off time
■ Floating load buck, floating load buck-boost and boost topology
controller
The reference inputs (REF_A and REF_B in Figure 5-1.) of the
hysteretic controller are provided by the reference DACs as
illustrated in the top level block diagram (see Figure 3-1. on page 3).
The hysteretic control function output is generated by comparing
the feedback value to two thresholds. Going below the lower
threshold turns the switch ON and exceeding the upper threshold
turns the switch OFF as shown in Figure 5-1. The output current
waveforms are shown in Figure 5-2.
The hysteretic controller also controls the minimum on-time and
off-time. This circuit prevents oscillation at very high frequencies;
which can be very destructive to output switches.
The output to the gate drivers is gated by the Trip, DIM and
Enable signals. The Enable signal is a direct result of the enable
bit in the control register for the hysteretic controller.
The Trip signal can be any digital signal that follows TTL logic
(logic high and logic low). It is an active high input.
The DIM Modulation signal is the output of the dedicated
modulators that are present in the power peripherals, or any
other digital modulation signal.
