Introduction

KA5Q0565RTYDTU is a Portable Timing Unit (PTU) designed for AC-DC-AC, off-line switcher power supply applications. It is a high precision digital timing controller that combines both a high speed counting unit (HSCU) and a low speed counting unit (LSCU) with an on board EEPROM. The device is a complete, low-power, miniature embedded timer that enables complete timing solutions to be implemented with a single device.

Features

KA5Q0565RTYDTU has a range of features that suit AC-DC-AC, offline switcher power supplies applications. The features include:• High precision scaler capable of counting pulses up to 1MHz.• On-board EEPROM memory for fast program execution and storing user data.• Temperature compensated CPU core for low power consumption.• Small size for ease of implementation.• Highly configurable for use in a wide range of applications.• Internal power-on reset (POR) and watch dog timer (WDT) for added system robustness.• Power failure detection and alternate power supply inputs.• Low EMI operation.• Low noise low DRP drain junction for enhanced circuit performance.

Application and Working Principle

KA5Q0565RTYDTU is designed for use in AC-DC-AC, offline switcher power supply applications. The device is specifically designed to provide accurate timing, control and monitoring functions in a number of applications including dc-dc converters, ac-dc inverters and step-down converters. In these applications, the device will typically be used to monitor the peak current, voltage and temperature of a switcher IC supply rail, thereby providing accurate control and monitoring of the switcher IC charge pump operation.In this type of application, the device will generally be placed in the feedback loop of the converter and will typically count pulses from an internal oscillator or from a converter output, as well as count pulses from a reference voltage or temperature signal. The HSCU and LSCU can then be used to measure the delta T of each pulse, thereby providing the converter with a variable frequency output in order to facilitate accurate power control and monitoring.In summary, the KA5Q0565RTYDTU is an advanced portable timing unit that is specifically designed for use in AC-DC-AC, offline switcher power supply applications. It features a low power, high precision scaler, on-board EEPROM, temperature compensated CPU core, power failure detection and low EMI operation. The device provides accurately timed control and monitoring in a single, low power package and is highly configurable for use across a range of applications.
