Sanyo LA5633 Specifications

Ordering number : ENN5969A

D2001TN (OT)/O3098RM (OT) No. 5969-1/7

Overview

The LA5633 is a low-saturation regulator IC designed for
use in satellite broadcast tuners (such as tuners for the
Japanese BS and CS systems) and provides four
controllable outputs.

Applications

• Power supply systems in BS/CS tuners

• Audio Video (AV) equipment that includes any type of
satellite broadcast tuner

• Miniature electronic equipment

Functions

• Built-in four regulators of low-saturation output
(15.7 V/350 mA, 9 V/250 mA, 12 V/100 mA,

5 V/650 mA)

• Output on/off control (active low)

• On-chip thermal protection and overcurrent protection
circuits

Features

• Provides all four voltages required by BS/CS tuners, and
thus can contribute to end product miniaturization.

•VO1 can be controlled independently, and VO2, VO3,
and VO4 are controlled together, thus providing a high
degree of flexibility in system design.

• The adoption of a low-saturation regulator circuit
reduces internal power dissipation.

• Provides 3 inputs to make both low-power design and
thermal design easy.

Function Table

This IC operates as listed in the table under the condition that VIN1 ≥ VIN2 ≥ VIN3.

• H and L in the EN column correspond to high and low input voltage levels, respectively.

• H and L in the VOcolumn correspond to the output on voltage and the output off voltage, respectively.

• The output voltages are controlled independently by the EN lines as follows: EN1 controls VO1, and EN2 controls
VO2, VO3, and VO4 in parallel.

• When a given EN is open, the corresponding output will be on.

Usage Notes

• GND1 and GND2 are connected through the IC substrate, and must be connected to the lowest potential in the system
and must be connected to identical potentials.
(The functions and characteristics of this IC are not guaranteed if GND1 and GND2 are connected to different potentials.)

• The rise and fall of the VIN1, VIN2, and VIN3 voltages must be simultaneous, and none of these pins may be either left
open or connected to ground.

• If either VIN1 or VIN2 are open or at a voltage lower than the stipulated voltage, then the VO1 through VO4 outputs
will be forcibly turned off to protect the IC.

• The output capacitors CO1 and CO4 must be at least 100 µF, and CO2 and CO3 must be at least 47 µF. Capacitors with
low temperature coefficients must be use to prevent oscillation at low temperatures.

• To assure stable operation, the input capacitors CIN1 to CIN3 and the output capacitors CO1 to CO4 must be placed as
close to the IC as possible.

• The NC pins (pins 1 and 14) must not be used.

• The output voltage VO4 can be adjusted by connecting resistors from the CN pin (pin 11) to either VO4 or to GND2.
— To lower VO4: Add resistor RA between CN and VO4.
— To raise VO4: Add resistor RB between CN and GND2.

Also note that external noise suppression and ripple rejection can be improved by adding an external capacitor at
VO4. However, care is required to assure that the system stability (phase margin) is adequate.

• Note that these power supplies can be influenced by load fluctuations in the other power supplies.
