General Description

The Supertex HV9120 is a Switch Mode Power Supply

(SMPS) controller subsystem that can start and run directly

from almost any DC input, from a 12V battery to a rectified

and filtered 240V AC line. It contains all the elements

required to build a single-switch converter except for the

switch, magnetic assembly, output rectifier(s) and filter(s).

A unique input circuit allows the HV9120 to self-start directly

from a high voltage input, and subsequently take the power

to operate from one of the outputs of the converter it is

controlling, allowing very efficient operation while maintaining

input-to-output galvanic isolation limited in voltage only by

the insulation system of the associated magnetic assembly.

A ±2% internal bandgap reference, internal operational

amplifier, very high speed comparator, and output buffer

allow production of rugged, high performance, high efficiency

power supplies of 50W or more, which can still be over 80%

efficient at outputs of 1.0W or less. The wide dynamic range of

the controller system allows designs with extremely wide line

and load variations with much less difficulty and much higher

efficiency than usual. The exceptionally wide input voltage

range also allows better usage of energy stored in input

dropout capacitors than with other PWM ICs. Remote on/off

controls allow either latching or nonlatching remote shutdown.

During shutdown, the power required is under 6.0mW.

For detailed circuit and application information, please

refer to application notes AN-H13, AN-H21 to AN-H24.

Detailed Description

The pre regulator/startup circuit for the HV9120 consists of

a high-voltage n-channel depletion-mode DMOS transistor

driven by an error amplifier to form a variable current path

between the VIN terminal and the VDD terminal. Maximum

current (about 20 mA) occurs when V

= 0, with current re-

ducing as V

rises. This path shuts off altogether when V

rises to somewhere between 7.8 and 9.4V, so that if V

held at 10 or 12V by an external source (generally the sup-

ply the chip is controlling), no current other than leakage is

drawn through the high voltage transistor. This minimizes

dissipation.

An external capacitor between VDD and VSS is generally

required to store energy used by the chip in the time be-

tween shutoff of the high voltage path and the VDD supply’s

output rising enough to take over powering the chip. This

capacitor should have a value of 100X or more the effective

gate capacitance of the MOSFET being driven, i.e.,

STORAGE

≥ 100 x (gate charge of FET at 10V)

as well as very good high frequency characteristics. Stacked

polyester or ceramic caps work well. Electrolytic capacitors

are generally not suitable. A common resistor divider string

is used to monitor V

for both the undervoltage lockout cir-

cuit and the shutoff circuit of the high voltage FET. Setting

the undervoltage sense point about 0.6V lower on the string

than the FET shutoff point guarantees that the undervoltage

lockout always releases before the FET shuts off.

Pre regulator

is used, or a 510 to 680KΩ resistor if V

will be 12V. A

precision resistor is not required; ±5% is fine.

The clock oscillator of the HV9120 consists of a ring of

CMOS inverters, timing capacitors, a capacitor discharge

FET, and a frequency dividing flip-flop. A single external re-

sistor between the OSC IN and OSC OUT pins is required

to set oscillator frequency (see graph).

One difference exists between the Supertex HV9120 and

competitive 9120s: The oscillator is shut off when a shutoff

command is received. This saves about 150µA of quiescent

current, which aids in the construction of power supplies

to meet CCITT specification I-430, and in other situations

where an absolute minimum of quiescent power dissipation

is required.

Clock Oscillator

Reference

The Reference of the HV9120 consists of a stable bandgap

reference followed by a buffer amplifier which scales the

voltage up to approximately 4.0V. The scaling resistors of

the reference buffer amplifier are trimmed during manufac-

ture so that the output of the error amplifier, when connected

in a gain of -1 configuration, is as close to 4.0V as possible.

This nulls out any input offset of the error amplifier. As a con-

sequence, even though the observed reference voltage of a

specific part may not be exactly 4.0V, the feedback voltage

required for proper regulation will be.

A ≈ 50KΩ resistor is placed internally between the output

of the reference buffer amplifier and the circuitry it feeds

(reference output pin and non-inverting input to the error

amplifier). This allows overriding the internal reference with

a low-impedance voltage source ≤6.0V. Using an external

reference reinstates the input offset voltage of the error am-

plifier, and its effect of the exact value of feedback voltage

Bias Circuit

An external bias resistor, connected between the bias pin

and VSS is required by the HV9120 to set currents in a se-

ries of current mirrors used by the analog sections of the

chip. Nominal external bias current requirement is 15 to

20µA, which can be set by a 390 to 510KΩ resistor if a 10V
