■General Description

■Features

PFC/DC-DC Systematic Combo Power IC

STR-E1555

mode power supply (SMPS). Start-up circuit and a controller

of PFC and DC/DC parts are built in one chip. In addition,

this chip and Power MOS FET for DC/DC part are

incorporated into a SIP package thanks to High Voltage BCD

Process technology. STR-E1555 includes the System of

Prioritized PFC-Startup for prevention of Start-up Error.

design of High Efficiency and Low EMI power supply

system with a small number of discrete components.

AC input compensation reduces power consumption at

standby, STR-E1555 is optimum for downsizing and

standardization of power supply system.

enables to configure the optimum system for diverse PFC

outputs because the power MOSFET is provided externally.

● Integrated PFC Control Block

1. Critical Conduction Mode for High Efficiency and Low

2.Built-in Multiplier with AC input compensation

● High Efficiency and Low EMI DC/DC Control Block

1. Multi Mode Control

● PFC <=> DC/DC Part Harmonized Operation System

1. PFC Priority Start-up System for Prevention of Start-up

2. Auto Standby System with AC input compensation

3. PFC operation stops automatically with delay timer

● Protection Functions

1. Over Current Protection with AC input voltage

2. High Speed Over Voltage Protection for PFC part (OVP)

3. Over Current Protection for DC/DC part (OCP)

4. Over Load Protection for DC/DC part (OLP)

5. Input Power Limitation System at Intermittent Oscillation

6. Thermal Shut Down (TSD)

7. External Latch Protection by External Signal（ELP）

■Line-up

Additionally, since built-in Auto Standby Function with

(1) Quasi Resonant

(2) PWM（100kHz）with Frequency Jitter

(3) Low Frequency Operation

STR-E1555 is a Hybrid IC power

Our proprietary Multi Mode Control system simplifies the
