MCP1663

High-Voltage Integrated Switch PWM Boost Regulator with UVLO

Features

General Description

• 36V, 400 mΩ Integrated Switch

• Up to 92% Efficiency

The MCP1663 device is a compact, high-efficiency,

fixed-frequency, non-synchronous step-up DC-DC

converter which integrates a 36V, 400 mΩ NMOS

switch. It provides a space-efficient high-voltage

step-up power supply solution for applications powered

by either two-cell or three-cell alkaline, Ultimate

Lithium, NiCd, NiMH, one-cell Li-Ion or Li-Polymer

batteries.

• Output Voltage Range: up to 32V

• 1.8A Peak Input Current Limit:

- I_OUT> 375 mA @ 5.0V V_IN, 12V V_OUT

- I_OUT> 200 mA @ 3.3V V_IN, 12V V_OUT

- I_OUT> 150 mA @ 4.2V V_IN, 24V V_OUT

• Input Voltage Range: 2.4V to 5.5V

• Undervoltage Lockout (UVLO):

- UVLO @ V_INRising: 2.3V, typical

- UVLO @ V_INFalling: 1.85V, typical

• No Load Input Current: 250 µA, typical

The integrated switch is protected by the 1.8A

cycle-by-cycle inductor peak current limit operation.

There is an output overvoltage protection which turns

off switching in case the feedback resistors are

accidentally disconnected or the feedback pin is

short-circuited to GND.

• Sleep mode with 0.3 µA Typical Shutdown

Quiescent Current

Low-voltage technology allows the regulator to start-up

without high inrush current or output voltage overshoot

from a low-voltage input. The device features a UVLO

which avoids start-up and operation with low inputs or

discharged batteries for two cell-powered applications.

• PWM Operation with Skip Mode: 500 kHz

• Feedback Voltage Reference: V_FB= 1.227V

• Cycle-by-Cycle Current Limiting

• Internal Compensation

For standby applications (EN = GND), the device stops

switching, enters sleep mode and consumes 0.3 µA

(typical) of input current.

• Inrush Current Limiting and Internal Soft Start

• Output Overvoltage Protection (OVP) in the event

of:

MCP1663 is easy to use and allows creating classic

boost, SEPIC or flyback DC-DC converters within a

small Printed Circuit Board (PCB) area. All

compensation and protection circuitry is integrated to

minimize the number of external components. Ceramic

input and output capacitors are used.

- Feedback pin shorted to GND

- Disconnected feedback divider

• Overtemperature Protection

• Easily Configurable for SEPIC, Cuk or Flyback
