1 / 8 page UNISONIC TECHNOLOGIES CO., LTD P1786 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 8 Copyright © 2007 Unisonic Technologies Co., Ltd QW-R103-038.A PWM CONTROL 3A STEP-DOWN CONVERTER DESCRIPTION UTC P1786 consists of 3A step-down switching regulator control which include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc with PWM. UTC P1786 can provide low-ripple power, high efficiency, and excellent transient characteristics. An enable function, an over current protect and short circuit protect function are built inside, so the operation frequency can be reduced from 300KHz to 30KHz when OCP or SCP happens. The PWM control circuit can vary the duty ratio linearly from 100 down to 0%. This converter also includes an error amplifier circuit as well as a soft-start circuit that prevents overshoot at startup. Also, to minimum external component counts for an internal compensation block is built in. These ICs can work as step-down switching regulators with the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally. They provides such outstanding features: low current consumption. It is also suitable for the operation via an AC adapter because this converter accommodate an input voltage up to 23V. FEATURES * Input voltage: 3.6V ~ 23V * Output voltage: 0.8V ~ VCC * Duty ratio: 0% to 100% PWM control * Oscillation frequency: 300KHz typ. * Soft-start, current limit, enable function * Thermal shutdown function * Built-in internal SW P-channel MOS SOP-8 *Pb-free plating product number: P1786L ORDERING INFORMATION Ordering Number Normal Lead Free Plating Package Packing P1786-S08-R P1786L-S08-R SOP-8 Tape Reel P1786-S08-T P1786L-S08-T SOP-8 Tube |
