RHFL4913 ADJUSTABLE VERSION

DEVICE DESCRIPTION

The RHFL4913 Adjustable contains a PNP type power element controlled by a signal resulting from

amplified comparison between the internal temperature compensated Band-Gap and the fraction of the

desired Output Voltage value obtained from an external resistor divider bridge. The device is protected by

several functional blocks.

ADJ pin

The Load output voltage feed-back comes from an external divider resistor bridge middle point connected

to ADJ pin (allowing all possible output voltage settings as per User’s desire) established between Load

terminals.

INHIBIT ON-OFF Control

By setting INHIBIT pin TTL-High, the Device switches off the Output Current and Voltage. Device is ON

when INHIBIT pin is set Low. Since INHIBIT pin is internally pulled down, it can be left floating in case

Inhibit function is not utilized.

Overtemperature protection

A temperature detector internally monitors the power element junction temperature. The Device goes

OFF when approx. 175°C are reached, returning to ON mode when back to approx. 40°C. Combined with

other protection blocks, it protects the Device from destructive junction temperature excursions in all load

conditions. It is worth noting that when internal temperature detector reaches 175°C, the active power

element can be at 225°C: Extensive operation under these conditions far exceeds Maximum Operation

Ratings and Device reliability cannot be granted.

Overcurrent protection

An internal non-fold back Short-Circuit limitation is set with I

SHORT

> 3.8A (V

is 0V). This value can be

downwards modified by an external resistor connected between I

pin and V

pin, with a typical value

range of 10kΩ to 200kΩ. To keep excellent V

regulation, it is necessary to set I

SHORT

1.6 times greater

than the maximum desired application I

. When I

reaches I

SHORT

– 300mA, the current limiter overrules

Regulation and V

starts to drop and OCM flag is risen. When no current limit adjustment is required, I

pin must be left unbiased (as it is in 3pin packages).

OCM pin

Goes Low when current limit starts to be active, otherwise V

OCM

= V

. It is buffered and can sink 10mA.

OCM pin is internally pulled-up by a 50 kΩ resistor.

Alternates to: RHFL4913 is recommended to replace all Industry Positive Regulators due to its

exceptional Radiation performance. To replace 3-terminal Industry devices, use RHFL4913 Fixed

Voltage versions.

APPLICATION INFORMATION

Adjusting Output Voltage: R2 resistor must be connected between V

and ADJ. R1 resistor must be

connected between ADJ and Ground. Resistor values can be derived from the following formula:

= V

ADJ

x R1 / (R1+ R2)

ADJ

is 1.22V, controlled by the internal temperature compensated Band Gap block.

The minimum Output voltage is therefore 1.22V and minimum Input voltage is 3V.

The RHFL4913 Adjustable is functional as soon as V

- V

voltage difference is slightly above the power

element saturation voltage. The Adjust pin to Ground resistor must not be bigger than 10kΩ to keep the

output feed-back error below 0.2%. A minimum 0.5mA I

must be set to ensure perfect “no-load”

regulation. It is advisable to dissipate this current into the divider bridge resistor. All available V

pins shall

always be externally interconnected, same thing for all available V

pins, otherwise Device stability and

reliability cannot be granted. The INHIBIT function switches off the output current in an electronic way,

that is very quickly. According to Lenz’s Law, external circuitry reacts with LdI/dt terms which can be of

high amplitude in case somewhere an inductance exists. Large transient voltage would develop on both

Device terminals. It is advisable to protect the Device with Schottky diodes preventing negative voltage

excursions. In the worst case, a 14V Zener diode shall protect the Device Input. The Device has been
