Low height and Creeping distance of 4mm or longer

650 V, 1.9 Ω, PWM Off-Line Switching Regulator IC

STR-V653

April 25, 2013

General Descriptions

Package

SIP8L

The STR-V653 is a power IC for switching power supplies,

incorporating a power MOSFET and a current mode PWM

controller IC in one package.

The SIP8L full mold package features low height and

creeping distance of 4mm or longer between high and low

voltage pin bases.

To achieve low power consumption, the product includes a

startup circuit and a standby function in the controller.

The switching modes are automatically changed according

to load conditions so that the PWM mode is in normal

operation and the burst mode is in light load condition.

The rich set of protection features helps to realize low

component counts, and high performance-to-cost power

supply.

 Protection features

▫ Overcurrent Protection function (OCP): pulse-by-pulse, with

input compensation function

▫ Overvoltage Protection function (OVP): latched shutdown

▫ Overload Protection function (OLP): auto-restart, with timer

▫ Thermal Shutdown function (TSD): latched shutdown

Features

 SIP8L package (2.54 pitch, straight lead): Creeping

distance of 4mm or longer between high voltage and low

voltage pin bases. Low height of less than 12 mm from

PCB (Printed Circuit Board)

 Current mode PWM control

 Auto Standby function: improves efficiency by burst

mode operation in light load

▫ Normal operation: PWM mode

Electrical Characteristics

 Operation Frequency, f_OSC(AVG)(typ) = 67 kHz

 Power MOSFET

▫ Light load operation: Burst mode

 No load power consumption < 25 mW

 Brown-In and Brown-Out function: auto-restart, prevents

excess input current and heat rise at low input voltage

 Random Switching function: reduces EMI noise, and

simplifies EMI filters

 Slope Compensation function: avoids subharmonic

oscillation

 Leading Edge Blanking function

V_DSS(min) = 650 V

R_DS(ON)(max) = 1.9 Ω

Applications

 Standby power supply

 Home appliances

 Digital appliances

 Office automation (OA) equipment

 Industrial apparatus

 Communication facilities

 High Speed Latch Release function
