DESCRIPTION

TJ1051 is a highly integrated solution for SMPS

applications requiring constant voltage and constant

current mode.

PIN CONNECTIONS (TOP VIEW)

SOP-8

SOT-23-6

TJ1051 integrates one voltage reference, two operational

amplifiers (with ORed ouputs - common collectors), and

a current sensing circuit.

The voltage reference combined with one operational

amplifiers makes it an ideal voltage controller, and the

other low voltage reference combined with the other

operational amplifier makes it an ideal current limiter

for output low side current sensing.

The current threshold is fixed and precise.

The only external components are :

●

Block Diagram

1.210V

A resistor brideg to be connected to the output

of the power supply (adaptor, battery charger)

to set the voltage regulation by dividing the

desired output voltage to match the internal

voltage reference value.

Vcc

Out

●

A sense resistor having a value and allowable

dissipation power which need to be chosen

Vctrl

according to the internal vlotage threshold.

Optional compensation components (R and C).

●

200mV

Vsense

● BATTERY CHARGERS

● ADAPTERS

TJ1051, is ideal for smallest package available, is ideal for space shrinked applications such as

battery chargers and adaptors.
