TOPSwitch Family Functional Description

TOPSwitchisaselfbiasedandprotected

linear control current-to-duty cycle

converter with an open drain output.

High efficiency is achieved through the

Auto-restart

MAX

use of CMOS and integration of the

Slope = PWM Gain

-16%/mA

maximumnumberoffunctionspossible.

CMOS significantly reduces bias

currents as compared to bipolar or

discretesolutions. Integrationeliminates

externalpowerresistorsusedforcurrent

sensing and/or supplying initial start-up

bias current.

MIN

During normal operation, the internal

output MOSFET duty cycle linearly

decreases with increasing CONTROL

pin current as shown in Figure 4. To

implement all the required control, bias,

and protection functions, the DRAIN

and CONTROL pins each perform

several functions as described below.

Refer to Figure 2 for a block diagram

and Figure 6 for timing and voltage

waveformsoftheTOPSwitchintegrated

circuit.

Control Voltage Supply

CONTROL pin voltage V_Cis the supply

or bias voltage for the controller and

driver circuitry. An external bypass

capacitorcloselyconnectedbetweenthe

CONTROL and SOURCE pins is

requiredtosupplythegatedrivecurrent.

The total amount of capacitance

connected to this pin (C_T) also sets the

auto-restart timing as well as control

loop compensation. V_Cis regulated in

either of two modes of operation.

Hysteretic regulation is used for initial

start-up and overload operation. Shunt

regulation is used to separate the duty

cycleerrorsignalfromthecontrolcircuit

supply current. During start-up, V_C

current is supplied from a high-voltage

switched current source connected

internally between the DRAIN and

CONTROL pins. The current source

provides sufficient current to supply the

control circuitry as well as charge the

total external capacitance (C_T).
