RP402x Series

High Efficiency Small Packaged Step-up DC/DC Converter

NO.EA-317-150121

OUTLINE

The RP402x is a CMOS-based high efficiency step-up DC/DC converter with synchronous rectifier. The device

can start up with low voltage of typically 0.7 V which is ideal for the applications powered by either one-cell or

two-cell alkaline, nickel-metal-hydride (NiMH) or one-cell Lithium-ion (Li+) batteries.

Internally, the RP402x consists of an oscillator, a reference voltage unit with soft start, a chip enable circuit, an

error amplifier, phase compensation circuits, a slope circuit, a PWM control circuit, a start-up circuit, a

PWM/VFM mode control circuit, internal switches and protection circuits.

The RP402x is employing synchronous rectification for improving the efficiency or rectification by replacing

diodes with built-in switching transistors. Using synchronous rectification not only increases circuit performance

but also allows a design to reduce parts count.

The RP402x is available in either internally fixed output voltage type or adjustable output voltage type. The

RP402xxxxx is the internally fixed output voltage type. The RP402x00xx is the adjustable output voltage type,

which allows output voltages that range from 1.8 V to 5.5 V via an external divider resistor.

The RP402x provides the forced PWM control and the PWM/VFM auto switching control. Either one of these

can be selected by inputting a signal to the MODE pin. The forced PWM control switches at fixed frequency

rate in low output current in order to reduce noise. Likewise, the PWM/VFM auto switching control automatically

switches from PWM mode to VFM mode in low output current in order to achieve high efficiency. The RP402N

is available in the PWM/VFM auto switching control. However, the RP402N is also available in the forced PWM

control as a custom-designed IC^*1.

The RP402x has a soft-start time of typically 0.5 ms.

The RP402x features the complete output disconnect shutdown option and the input-to-output bypass

shutdown option. The RP402xxxxA/ B/ E/ F incorporates the complete output disconnect shutdown option,

which allows the output to be disconnected from the input. The RP402xxxxC/ D/ G/ H incorporates the input-

to-output bypass shutdown option, which allows the output to be connected to the input.

The RP402x is protected against damage by a short-current protection, an over-voltage lockout, an over

voltage protection, an anti-ringing switch and a latch-type protection. An anti-ringing switch prevents the

occurrence of noise when an inductor current reaches a discontinuous mode. The latch-type protection can

be released by switching the CE pin from high to low.

The RP402x is offered in a compact 5-pin SOT23-5^*1package or a 8-pin DFN(PLP)2020-8 package.
