SP6136 General Description

The SP6136 is a synchronous step-down switching regulator controller optimized for high efficiency. The part is designed to be especially attractive for single supply step down conversion from 5V to 24V. The SP6136 is designed to drive a pair of external NFETs using a fixed 600 KHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown, output short circuit protection, and overcurrent protection with UVLO, thermal shutdown, output short circuit protection, and overcurrent protection with auto restart. The device also features a PWRGD output and an enable input. The SP6136 is available in a space saving 16-pin QFN and offers excellent thermal performance.

The SP6136 has 13 features.The first one is 5V to 24V Input step down converter.The second one is Up to 7A output in a small form factor.The third one is Highly integrated design, minimal components.The fourth one is UVLO Detects Both VCC and VIN.The fifth one is Overcurrent circuit protection with auto-restart.The sixth one is U.S. Patent #6,922,041.The seventh one is Power Good Output, ENABLE Input.The eighth one is Maximum Controllable Duty Cycle Ratio up to 92%.The ninth one is Wide BW amp allows Type II or III compensation.The tenth one is Programmable Soft Start.The eleventh one is Fast Transient Response.The twelfth one is Available in Lead Free, RoHS Compliant 6-Pin QFN package.The thirteenth one is External Driver Enable/Disable.

The SP6136 is a fixed frequency, voltage mode, synchronous PWM controller optimized for high efficiency. The part has been designed to be especially attractive for single supply input voltages ranging between 5V and 24V.The heart of the SP6136 is a wide bandwidth transconductance amplifier designed to accommodate Type II and Type III compensation schemes. A precision 0.8V reference present on the positive terminal of the error amplifier permits the programming of the output voltage down to 0.8V via the VFB pin.The output of the error amplifier, COMP,compared to a 1V peak-to-peak ramp is responsible for trailing edge PWM control.This voltage ramp and PWM control logic are governed by the internal oscillator that accurately sets the PWM frequency to 600kHz.
