Product Overview
The TF22A is a low power primary switcher best suitable for Off-line SMPS battery
charger adapters, auxiliary power supplies for industrial systems and standby power
supplies for TVs or monitors. It consists of a dedicated current mode PWM controller
and a high-voltage Power MOSFET
The TF22A operates at fixed 60 kHz switching frequency. Its control circuitry provides
large VDD range desired in applications in which auxiliary power supply changes
are expected. It also provides over-voltage, over-current and over-temperature protection.
The TF22A is offered in 8-pin PDIP and SOIC narrow packages and operates over an
extended -40 °C to +85 °C temperature range.
