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
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.
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
▫ 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
 High Speed Latch Release function
