Features & Benefits
The HV9605 is ideally suited for small wattage SMPS such as those used in telephone terminals. The Start-Stop function
is a unique feature that allows a wide hysterises to eliminate oscillation caused by the voltage drop due to high telephone
line resistance in long loops
. Presently, systems manufacturers implement this Start-Stop function by using three resistors
and at least one bipolar transistor (preferably two transistors for desirable tolerance).
Features
Benefits
High Voltage BiCMOS Technology
Eliminates the need for an external start-up circuit, which is necessary to
conserve power.
More stable than voltage control.
Current Mode Control
49% duty cycle operation
Programmable START/STOP capability
Flyback converter is more stable if operated below 50%.
Turns IC off when battery falls below or rises above a pre-set value. This
eliminates oscillation or repeated turn-on and turn-off with long high
telephone lines.
Works with a wide range of input voltages in telecommunication systems
worldwide. Operates satisfactorily in long loop conditions.
Extremely low power in stand-by mode, mandatory for ISDN.
15V to 250V input range

DD
supply operation
Provides low power consumption necessary for telecommunication systems.
Helps provide low power consumption compared to 12V or other
higher input voltage ICs. Reduces system cost by eliminating an auxiliary
transformer winding for V
DD
in systems that have 5V output.
Increases system accuracy, high bandwidth results in fast response to load
and line changes.
Low reference voltage makes it easier to work with lower output voltages, and
achieve good output voltage regulation.
1.0 MHz low offset error amplifier
1% feedback voltage reference
Output driver optimized for under 10W operation
Low driver output impedance with V
DD
= 0V
Under voltage lockout
Fast ( 120nsec max. ) over current shutdown
Provides optimum efficiency for this level of operation.
Improved noise immunity since gates are pulled down.
Prevents MOSFET switch from drawing excessive current and being damaged.
Allows for small size external FETS to be used.
