AEROFLEX PLAINVIEW'S PW5032 RadHard HIGH SPEED PWM CONTROLLER ADDED TO THEIR RadHard PRODUCT LINE

Aeroflex Plainview (NASDAQ: ARXX), announces an addition to their RadHard-by-Design PWM controller. The PWM5032 high-speed, low power controller joins the PWM5031 which is currently in production. The RadHard PWM Controller was developed in partnership with Johns Hopkins University/Applied Physics Lab and the Technology Applications Group for the Mars Technology program, part of NASA’s Mars Exploration Program. Aimed at the military, defense and commercial satellite markets, the PWM5032 complements Aeroflex Plainview’s line of RadHard microelectronic power products.

The PWMs were designed using radiation-hardness techniques to insure the product meets radiation tolerance (>1M-Rad), provides the necessary features to implement DC to DC fixed frequency current or voltage mode control schemes with a minimal external parts count. Internally implemented low power dissipation circuits include under-voltage lockout, a precision voltage reference for accuracy at the error amp input, sleep and enable control pins, a “power good” indicator, logic to insure latched operation, selectable duty cycle control, and a dual totem pole output stage designed to source of sink high peak current.

The enhancement to the PWM5032, compared to the PWM5031, is an output stage driver that can operate and output 12 volts. This provides a higher drive voltage for applications that require control of larger external transistor when higher voltage converter designs are required. Both the PWM5031/PWM5032 have two logic level inputs for implementing shutdown functions; a SLEEP pin disables all chip functions and puts the chip into a very low power consumption mode, while the EN pin shuts down all functions except the reference, bias generators and auxiliary amplifier.
